Use "/commits/:sha/diff" as opposed to "/commit/:sha", keeping in line
with existing api urls (e.g. "/projects/:id", etc.)

Fix 500 error resulting from a diff api call with an invalid commit hash

Move "/commits/:sha/blob" to "/blobs/:sha", leaving the old path for
backwards compatibility.

Add ability to get a single commit via "/commits/:sha"

-Some changes around calling origional methods for !for_fork? merge requests. Other changes to follow

-Disable observers post test run
-Allow db:seed_fu RAILS_ENV=test to be run more than once without error
-fix diffs_in_between, was passing in the default_options for grit, but grit in this case doesn't take options, fixed the test to actually fail if the incorrect diffs are returned
-make notes/commits render against proper project
-MR discussion file links should reference note's project
-Added tests for commit links on edit merge request
-fixes edit issues (canceling an edited mr, updating an edited mr)
-updates tests with checks for source code updates
-still forked_merge_requests.feature (project_forked_merge_requests) test not passing (commented out -- "stable" not being set)

MR API: error on bad target_project

-If the target project id is specified and it is not the same as the project the request is being made on (the source), and the it isn't a fork of that project, error out, otherwise use it as the target
-Fixes some busted (but hidden) test cases

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
