* implement a fix for tags being found in code blocks

still needs polish, consider this a rough draft

* refactor to reuse a local function

uses CheckWrappedInCode to check that there are no code blocks that surround the tag being parsed

* Add more test coverage of MessageHelper.ParseTags

* reset indexes for @ here mention

* add a test case to catch error fixed from prev commit

* wip commit of most test cases working

* fix the Enclosed in block util method

* code cleanup

* lint whitespace

* lint brackets for single line if blocks

* move messagehelpertests to the new unit test dir

* expose internals to the unit test project

this seems to have been breaking the build, since CI would build the merged branch, where rest wasn't exposed to the unit tests

* Implement Quote Formatting

Adds support for block quote text formatting. This feature is currently only implemented in the Canary client.
This formatting adds a "> " to each new line from the input text.

* add > char to character sanitization

* change assumptions around whitespace strings

* add blockquote (>>>) formatting + test

* Squashed commit of test rewrite changes

fix missing priority speaker flag

rewrite the TestChannelPermissionModify test

add test for GuildPermission modify

separate unit and integration tests, start writing channel and guild permission tests

copy over the color tests

copy over the emote tests

copy the token utils tests

make the mocked entities sealed classes

copy the TypeReaderTests class

properly dispose the CommandService in the TypeReaderTests

start writing tests for EmbedBuilder and related classes

test that properties throw ArgumentException when invalid

add tests for the embed length property

fix bug in value validation of EmbedFieldBuilder

hey, these tests actually found a bug!

add tests for the MentionUtils class

add tests for the Format util class

remove all of the old tests

add analyzer tests (copied from old tests)

add tests for the SnowflakeUtils class

add integration tests

these get around the issue of state persisting between tests by creating and deleting a guild for each set of tests. these shouldn't be run excessively because of the rate limits, but should be fine every now and then

remove unnecessary launchSettings.json

update outdated string

don't create a new guild each time, as that can result in errors

this can happen if a bot creates too many guilds without properly deleting them

add some tests that show that guild can be modified

await async assert

add more measures that created channels are deleted when done

remove "Test" prefix from test method names

I think that this prefix when already displayed under a class with a suffix of "Tests" is redundant

Remove mention of old test project

fix an issue from forgetting to await Assert.ThrowsAsync

explicitly disable parallelization on integration tests

add test for GuildPermission modify

separate unit and integration tests, start writing channel and guild permission tests

fix test that would break in different timezones

enable the integration tests (only on dev branch)

* Update mocked channels for changed SendFileAsync signature

* comment out the integration tests from the build script

no bot token is provided to this script, and use of integration tests in CI is questionable here

* force rebuild because Azure linux build broke

* fix missing priority speaker flag

* rewrite the TestChannelPermissionModify test

* Trim whitespace from tokens before logging in

This change trims whitespace characters from the supplied token before it is used to log in. Users can encounter this accidentally if they read their token from a file that ends with a blank line.

Leading whitespace will make the token invalid. Trailing whitespace or \n (not \r\n) will also fail to log in. \r\n (CRLF) doesn't fail because of the line break style for http request headers.

* revert trimming api token

* add check for whitespace or newline characters to existing token validation

Checks to see if a token contains any illegal characters, like whitespace or a newline. If it is, throws an ArgumentException warning the user that their token may be invalid.

I considered only checking the first and last character, but given that a token containing whitespace or a newline wouldn't work either I figured this made sense.

* removed unused usings

These were leftover from a previous approach using an ImmutableHashSet

* Add webhook url overload for DiscordWebhookClient

Adds an overloaded constructor for `DiscordWebhookClient` which accepts the webhook URL. This URL is parsed using a regex for the id and token. If the token is invalid an `ArgumentException` is thrown.

* add null or whitespace check

* add some tests for the new DiscordWebhookClient constructor

* make the Regex static, specify flags

* update regex to look for "discordapp"

* specify reason why exception is thrown despite regex match

* move parsing logic into new function for testing

* add a util method for padding base64 strings if they are not of an expected length

* return the original string if it already contains padding, do not throw

* add tests for padding method, and for token that needs padding

* improve bot token validation by trying to decode user id from token

Try to decode the user id from the supplied bot token as a way of validating the token. If this should fail, indicate that the token is invalid.

* Update the tokenutils tests to pass the new validation checks

* Add test case for CheckBotTokenValidity method

* lint: clean up whitespace

* Add check for null or whitespace string, lint whitespace

* fix userid conversion

* Add hint to user to check that token is not an oauth client secret

* Catch exception that can be thrown by GetString

* Refactor token conversion logic into it's own testable method

* Update the minimum bot token length to 58 char

- Updates the minimum length of a bot token to be 58 characters. An older 58 char bot token was found by Moiph
- Makes this value an internal const instead of a magic number

* update the TokenUtils tests for 58 char min

* Initial set of dispose implementations

Not handled yet:
- Discord.Net.Websocket/Entities/SocketGuild
- Discord.Net.Tests

* Refactor DiscordSocketClient init into ctor

This way we remove an IDisposableAnalyzer warning for not disposing
the client when we set the client variable.

* Dispose of clients when disposing sharded client

* Finish implementing IDisposable where appropriate

I opted to use NoWarn in the Tests project as it wasn't really necessary
considering that our tests only run once

of fixing bugs.

* Fix bugs in emote parser

* Added unit tests for emotes

* initial commit

* Add GuildPermission tests for constructor and modify parameters

* Fixed GuildPermission All value. Previous value had an additional digit that would still resolve to correct permission flags, but raw value would be incorrect. This matches the result of the sum of all GuildPermission flags

* Added raw value check to guild permission modify tests

* Add ChannelPermissions tests

* Changed Guild#DefaultChannel to resolve the first accessible channel

Resolves #776

This change is inline with hammerandchisel/discord-api-docs#329

RestGuild#DefaultChannelId is now obsolete and will throw a
NotSupportedException.

* RestGuild#DefaultChannelId will fall back to the guild ID

Adding an exception here would be a breaking change, so this was agreed
to fall back to the previous behavior, which would just return the guild
ID.

This provides tests to ensure the following:
- Creating a Color
- Creating a Default Color
- Accessing a Color's Raw Value
- Accessing a Color's translated RGB values

* Add support for audit log reasons

* Made changes per discussion
