* 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

This reverts commit 7237c6b3bf.
