Add support for external wikis
## What does this MR do?
This MR adds the possibility to replace the link to the internal wiki of gitlab with a custom link.
Currently this is realised as a service.
## What Use Case does this MR solve?
In my Company we already have a wiki System (Confluence).
We have a policy to use the existing wiki, so we can't switch to the internal wiki Gitlab provides.
This currently only leaves us two choices:
1. Disable the gitlab wiki. That means we completly loose the connection between wiki and code from the gitlab ui.
2. Create a simple wiki page with a link to our external wiki and hope that no one uses the internal one.
Both solutions are not really good.
So what can be done to improve the situation while making it as easy as possible for new developers to access both, wiki and gitlab?
Replacing the wiki link kinda like the JIRA integration replaces the issues link looks like a good first step to me. :)
This can probably be extended later to completly prevent access to the internal wiki (currently that's still possible if you know the link) or maybe to check if the link really points to a wiki.

Restricted visibility levels - bug fix and new feature
This allows admin users to override restricted visibility settings when creating and updating projects and snippets, and moves the restricted visibility configuration from gitlab.yml to the web UI. See #1903.
## Move configuration location
I added a new section to the application settings page for restricted visibility levels. Each level has a checkbox, styled with Bootstrap to look like a toggle button. A checked box means that the level is restricted. I added a glowing text shadow and changed the background color for checked buttons because the default styles made it hard to distinguish between checked and unchecked. This image shows the new section with the "Public" box checked:
## Allow admins to override
To allow admin users to override the restricted visibility levels, I had to remove the `visibility_level` validation from the `Project` class. The model doesn't know about the `current_user`, which should determine whether the restrictions can be overridden. We could use the creator in the validation, but that wouldn't work correctly for projects where a non-admin user is the creator and an admin tries to change the project to a restricted visibility level.
The `Project::UpdateService` and `Project::CreateService` classes already had code to determine whether the current user is allowed to use a given visibility level; now all visibility level validation is done in those classes. Currently, when a non-admin tries to create or update a project using a restricted level, these classes silently set the visibility level to the global default (create) or the project's existing value (update). I changed this behavior to be more like an Active Model validation, where using a restricted level causes the entire request to be rejected.
Project and personal snippets didn't have service classes, and restricted visibility levels weren't being enforced in the model or the controllers. The UI disabled radio buttons for restricted levels, but that wouldn't be difficult to circumvent. I created the `CreateSnippetService` and `UpdateSnippetService` classes to do the same restricted visibility check that the project classes do. And since I was dealing with snippet visibility levels, I updated the API endpoints for project snippets to allow users to set and update the visibility level.
## TODO
* [x] Add more tests for restricted visibility functionality

See merge request !1655
This adds the functionality of replacing all images that were uploaded
to gitlab with inline images(base64) in emails.
This change fixes the broken images in emails that 7.8 introduced
Fix code preview theme setting for comments, issues, merge requests, and snippets
User color scheme was not being used: default white color scheme was always chosen. Also, default background for code in notes was always overriding the user color scheme.
Closes#1139
See merge request !357
Also preserve code preview color scheme in events dashboard.
Assign default colors to all code blocks shown as <pre class="code highlight [color_scheme]">
Closes#1139
Add new service classes to create and update project and personal
snippets. These classes are responsible for enforcing restricted
visibility settings for non-admin users.
Supports four different event types all bundled under the "note" event type:
- comments on a commit
- comments on an issue
- comments on a merge request
- comments on a code snippet
