Also removed the cloning of forms for note edits. Instead it just hides/shows the form seeing as it is already there

Closes #14094

Added specs for Issue#referenced_merge_requests

Added these while looking into https://gitlab.com/gitlab-org/gitlab-ce/issues/13651.

See merge request !3125

Add shortcut to toggle markdown preview

Allow to toggle markdown preview with shortcut `ctrl+shift+p` (`cmd+shift+p` on OSX).

- If the user is focused on a md textarea, `ctrl-shift-p` will show the preview, otherwise native browser event is fired
- The textarea is re-focused after disabling the preview tab
- Results of markdown render is cached for fast toggles

I'm on linux, so if someone can test it on OS X, it would be great!

Add a `gemojione:sprite` Rake task

This task will generate a standard and Retina sprite of all of the
current Gemojione Emojis, with the accompanying SCSS map.

It will not appear in `rake -T` output, and the dependent gems are not
included in the Gemfile by default, because this task will only be
needed occasionally.

Commit limits

Prevent timeouts when creating/viewing Merge Requests with many
commits. Also, reduce the number of commits shown in the UI from 500
to 100.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/14031

This MR avoids Unicorn timeouts in some places and takes 4.5 seconds
off load times in others, when manually testing with a 4500-commit
compare/MR in the linux repo. It does not limit the number of Commit
objects instantiated in memory, just the amount of HTML generated. It
seems that having 4500 commits objects is not a problem in itself. If
it ever becomes one we could do something for Commit objects like we
did for Diff (introduce a CommitCollection or something).

Bump poltergeist to `~> 1.9.0`



See merge request !3116

This fixes the remainder of the GitPushService specs.

These were broken by commit 21a05328.
Two JIRA tests remain broken but I can't quite figure out how to fix
them.

Retry failed tests

This is to make the CI builds more reliable due to large amount of timeouts and deadlocks recently.
