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

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

Closes #5534

1. Fix double bottom border if pagination
2. Fix broken search on forks page
4. Remove duplicate js logic
4. Remove unused show all link
5. Remove duplicate “no project” message in different views

After this merge request you can easily render shared projects template
with all necessary html/js included to make searchable list with
pagination. All you need to provide is controller that returns
projects list with seach nad pagination and render html form with
project-filter-form id and text field with filter_projects name.

Fixed bold issue with headings

Closes #13857

When a user tabs to the submit button (i.e., the "wrong" way), we
display a tooltip with the quick submit hotkey so they can learn the
"right" way.

Now it will work on any field inside that form, and it's easier to scope
new behavior, which is what we're adding next!

* Also refactor query to get projects accessible for current user.
  ProjectsFinder actually return public projects when no user is passed.
