This reverts commit d66148ef, reversing
changes made to cdb64a81.

This change needed to be reverted,
because not enough email clients support inline images.

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

* Less margin: the content appears as the text of the message.

* Streamlined footer: everything on one line, with a small separator.

* Zimbra (www.zimbra.com) chokes on HTML tables, and doesn't display
the content of the message. Switching to a simpler layout fixes the
issue.

Previously the content of the issue or merge request was missing from
the email.

Every email has a different way of showing a link to the discussion on
the website. We don't need this anymore, as we now have a standard
"View in GitLab" link in the footer of every email.

There was some funny syntax in merge request email templates. There was a ! before
the merge request number when there probably should be a #. This may be some carry over
from markdown but should not be in email templates.  There were also some capitalization
discrepancies among the subject lines. For those OCD people out there I standardized the
capitalization. :)

Forked MR's will print

Project:Branch <source_project_with_path>:<source_branch> -> <target_project_with_path>:<target_branch>

Non forked MR's will print

Branch <source_branch> -> <target_branch>

The good:

 - You can do a merge request for a forked commit and it will merge properly (i.e. it does work).
 - Push events take into account merge requests on forked projects
 - Tests around merge_actions now present, spinach, and other rspec tests
 - Satellites now clean themselves up rather then recreate

The questionable:

 - Events only know about target projects
 - Project's merge requests only hold on to MR's where they are the target
 - All operations performed in the satellite

The bad:

  -  Duplication between project's repositories and satellites (e.g. commits_between)

(for reference: http://feedback.gitlab.com/forums/176466-general/suggestions/3456722-merge-requests-between-projects-repos)

Fixes:

Make test repos/satellites only create when needed
-Spinach/Rspec now only initialize test directory, and setup stubs (things that are relatively cheap)
-project_with_code, source_project_with_code, and target_project_with_code now create/destroy their repos individually
-fixed remote removal
-How to merge renders properly
-Update emails to show project/branches
-Edit MR doesn't set target branch
-Fix some failures on editing/creating merge requests, added a test
-Added back a test around merge request observer
-Clean up project_transfer_spec, Remove duplicate enable/disable observers
-Ensure satellite lock files are cleaned up, Attempted to add some testing around these as well
-Signifant speed ups for tests
-Update formatting ordering in notes_on_merge_requests
-Remove wiki schema update
Fixes for search/search results
-Search results was using by_project for a list of projects, updated this to use in_projects
-updated search results to reference the correct (target) project
-udpated search results to print both sides of the merge request
