If you reopen a Merge Request and then try to update the source branch
it won't properly reload the code since the "reload_code" method still
checks if the MR is "opened" and not just "open" (which includes reopened)

Fix Social Account Block

If you have omniauth enabled, but don't have one of the "Social" providers enabled (GitHub, Twitter, Google), the "Social Accounts" sections shows up, but without icons. This occurred when I was testing Shibboleth. This fixes the issues by checking if there are any `enabled_oauth_providers` rather than if just `Gitlab.config.omniauth.enabled`. Not quite sure how to implement a test for this, but it works :).

Streamline the content of notification emails

In notification emails, the actual content of the email is often buried under several blocks of chrome — and may even be truncated or completely missing. Ideally, the notification emails would be like *real emails*: a short message of meaningful text, sent from the author of the change that triggered the notification.

This MR includes the following changes to notification emails:

* Remove much of the chrome (e.g. the "GitLab" header)
* Emphasize the content (no more small, grayed-out content)
* Add missing informations to the emails (issue description in "new issue" email, file name in "diff comment" email)
* Add a consistent "View in GitLab" link in the footer
* The assignee is displayed only if someone is assigned
* Fix a rendering bug when viewing emails with [Zimbra](http://www.zimbra.com/)

We use these patches at [Capitaine Train](http://www.capitainetrain.com), and it has been a surprisingly big productivity boost for us.
