Added tabindex to filter field

Based on however I changed the tabindex of the search field so that it goes search field -> filter field & then back to browser default. I dont think we should override the default tabindex of the page too much.

Closes #3706 

See merge request !3093

SSH keys settings

Closes #13860

See merge request !3034

Prior, we were double-checking `@keys.any?`, and unnecessarily assigning
`is_admin` in a view where it wasn't needed.

Button transparent colours

Closes #13860

Update spring to 1.6.4 to fix support for Bundler 1.11

See merge request !3083

A file called notes is loaded every ~15 seconds which checks for
updates to content on the page. This commit increases the polling
timeout over time (15, 30, 60, 120 seconds) and resets
it to 15 seconds if the AJAX call returns new notes

Fixes issue #13300

Lazy diffs

Needs https://gitlab.com/gitlab-org/gitlab_git/merge_requests/65

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/10785

-   Use Gitlab::Git::DiffCollection which limits the result set size.
    This avoids loading unnecessary data from Git/SQL into memory.
-   Remove left-over Grit timeout handling code.
-   Use Gitlab::Git::Count.lines to count lines in strings.
-   Use more iterators.
