* More tweaks to repo top panel

* undo hiding of compare button on master

* attempt to fix ci issue

* another ci attempt

* Add configuration flag SSH_EXPOSE_ANONYMOUS

If this flag (default True) is set to false, the SSH clone URL will only be exposed if the current user is signed in.

* Default SSH exposure set to false

To match GitHub and for security reasons, SSH URL exposure is disabled by default.
In addition to that. minor code changes have been applied.

* Integration test

    Feature for editing, creating, uploading and deleting files

We only handle branch selection for repo home and commits pages, so the
redirection URL is based on PageIsCommits

This commit improves templates readability, since all of them use consistent
indent with all template command blocks indented too.

1. Indents both HTML containers such as <div>, <p> and Go HTML template blocks
   such as {{if}} {{with}}

2. Cleans all trailing white-space

3. Adds trailing last line-break to each file

Merges repo/sidebar.tmpl with repo/header.tmpl and makes every repo page use
middleware.RepoRef() necessary to display information on this menu.

Just use secondary menu instead custom ".head.meta", which simplifies code.

Also do not display repo URL action when we are in subdirectory or viewing a
file.

This is more inline with way GitHub looks like and feels much more natural and
in style with rest of the interface.
