Unescape branch names in compare commit

The upgrade in GitLab v7.9 to Rails v4.1.9 caused all branch names in the compare commit mode to be escaped (e.g. `/` to `%2F`). The compare mode would not always work when comparing against branch names with a forward slash.

Opted to unescape the branch name rather than use a wildcard segment to prevent escaping slashes because it seems like a more sensible URL. The slashes in this case aren't really represented by a tree structure (e.g. /compare/one/two/branch..another/branch/here).

Allow primary email to be set to an email that you've already added.

Fixes gitlab-com/support-forum#106.

When the user sets their primary email to an email that they've already added to their account, this patch makes sure that secondary email record is destroyed, and a new email record is created for the old primary email. This is based on the assumption that in this case no email was meant to be deleted, but the user simply wanted to change which of their emails is primary.

Add application setting to restrict user signups to e-mail domains

This feature was requested long ago:

http://feedback.gitlab.com/forums/176466-general/suggestions/4118466-ability-to-register-only-from-ceratain-domains

This MR is based off !253 but changed to use application settings and use wildcard strings
to give more flexibility in pattern matching. Regexps seemed overkill and prone to mistakes.

Also note that validation is ONLY done on creation to prevent breaking existing users who do not have a whitelisted domain. However, this allows a user to sign-up and change his/her email to a non-whitelisted domain.

Screenshots:

Don't delete gitlab-test-fork folder after every test run

72a7febe added a forked repository cloned to `tmp/tests/gitlab-test-fork` but because it wasn't added to the list of folders not to delete every run, it was being cloned every run and adding extraneous console output.

Make Reply-To config apply to change e-mail confirmation and other notifications sent through Devise

Notifications sent through Devise were using the default From: address, and due to a broken test line nothing was actually being run.

The only way to customize the Devise Reply-To field is to use a custom mailer. Moved the e-mail configuration out of the initializers to accommodate this.

Closes #1556

Only restrict e-mail addresses upon creation

Add a page title to every page.

![You get a title, and you get a title; everyone gets a title!](https://i.imgflip.com/kvmq8.jpg)

The `page_title` helper pushes the provided string at the end of the title, but because of the order that layouts are rendered in by ActionView, the result is always this:

```
<title from view> |
<title from as specified in the controller or by its layout> |
<title from layouts/_head>
```

For example: `Merge Requests | GitLab.org / Gitlab Community Edition | GitLab`.

All a developer needs to know is to put a `page_title` call describing the page in question at the start of every template.

To get everything where I wanted it to go without too much duplication, I had to make some changes around layouts, sidebars and controllers.

More HTML::Pipeline filters

The big part of this MR is a feature that is intended to test the entire Markdown-parsing process from beginning to end. See `spec/support/markdown_feature.rb` and `spec/features/markdown_spec.rb`.

One big thing this MR fixes is not being able to type a `<` or `>` anywhere. It now gets properly escaped.

This MR also adds three more custom HTML::Pipeline filters:

### AutolinkFilter

Similar to the built-in Autolink filter in that it still uses Rinku for standard http and ftp links, but then does some further processing to allow auto-linking of any URI scheme. See internal issue https://dev.gitlab.org/gitlab/gitlabhq/issues/2239

### SanitizationFilter

Created a simple custom SanitizationFilter that sub-classes the default one and adds our custom whitelisting.

### TableOfContentsFilter

Adds the anchor links to each header. This removes some processing from our Redcarpet renderer.

Add link to services api doc.

Just a one-line change to link in the services api doc.

I'm curious though. Only gitlab-ci and hipchat are supported.  Would you accept a pull request for the other services? Actually I [submitted](http://feedback.gitlab.com/forums/176466-general/suggestions/7667256-add-api-calls-for-all-services-in-a-project) that last question to the feedback tool.
