Update ability to search in issue descriptions and comments

Add autofocus and tabindex.
links to issues on main dashboard
Update event helper to display target_iid in event title instead of target_id.

The event helper is used extensively within the dashboard atom feed, so by
fixing this, we fixed #303.
Fix for copy paste formatted text
Update installation doc to mention using https.
Extract gitlab-shell configuration note to gitlab-shell section.
notes count in 1 query for mr and commits
fix link to notes in merge request diff

http://localhost:3000/gitlabhq/gitlab-ci/merge_requests/1/diffs#note_316
scroll in such links doesn't work. It happens because  on page there are 2 elements with id="note_316" in changes and discussion.
Browser takes first for scroll.
This solution works because changes loads without diffs so tag with id="note_316" just one.
Diffs loads with discussions, but in this case diff tag would be first.
It is dirty but working solution.
