Fix highlighting of deleted lines in diffs.
Resolves internal https://dev.gitlab.org/gitlab/gitlabhq/issues/2498
Only needed until https://github.com/jneen/rouge/pull/297 is merged into
Rouge and the gem is updated in GitLab.
Forking `rouge`, releasing `gitlab-rouge` and using that gem wasn't an
option, since `gollum-lib` has `rouge` as a dependency, so it would get
included anyway, and which code we'd get would depend on the load order.

Set OmniAuth full_host parameter to ensure redirect URIs are correct
### What does this MR do?
This MR sets the OmniAuth `full_host` parameter to the configured GitLab URL to ensure the `redirect_uri` parameter is called with the right GitLab host.
### Why was this MR needed?
[OmniAuth attempts to grab the request URI](http://awesomeprogrammer.com/blog/2012/12/09/dealing-with-omniauth-redirect-uri-mismatch-invalid-port-number-gotcha/) and use that. If you set up a reverse proxy that terminates SSL at the Web server layer (e.g. https://gitlab.domain.com), omniauth will use the internal URL (e.g. http://my-host:8080) in its redirect URI unless all the Web server headers are properly set (e.g. `X-Forwarded-Port`, etc.). This is easy to forget or mess up, and it's better to ensure that OmniAuth has the right value from the start.
### What are the relevant issue numbers?
Closes#1967

Now we can simply loop through all themes, among other things.
This also removes the `dark_theme` / `light_theme` classes and the
`theme_type` helper, since they weren't used anywhere.
Until now, a user needed to first sign in with his LDAP identity and then manually
link his/her account with an omniauth identity from their profile.
Only when this is done can the user authenticate with the omniauth provider and at
the same time benefit from the LDAP integration (HTTPS authentication with LDAP
username/password and in EE: LDAP groups, SSH keys etc.).
This feature automates the process by looking up a corresponding LDAP person when a
user connects with omniauth for the first time and then automatically linking the LDAP
and omniauth identities (of course, like the existing allow_single_sign_on setting,
this is meant to be used with trusted omniauth providers).
The result is identical to a manual account link.
Add config initializers for other omniauth settings.
