Fix checkbox alignment in application settings

Add the form-control CSS class to the feature checkboxes on the application settings page to fix the vertical alignment with their labels.  See #2053.

Also add aria-describedby attributes to form controls that have a help text block (http://getbootstrap.com/css/#callout-help-text-accessibility).

This doesn't address the help text block for the twitter checkbox.  @dzaporozhets Do you want to keep the help text visible or would you rather put it in a dialog and hide it initially?

Update rugments, fixes #8900

Improve projects list

* Add search filtering for group projects
* Show all user projects on dashboard
* Refactor projects list into one view
* Hide big list of projects with 'Show all' button

For #2069

See merge request !1636

Increase timeout for Git-over-HTTP requests.

Fixes #2081 and https://gitlab.com/gitlab-org/gitlab-ce/issues/232.

Normal web requests are bound by the `Rack::Timeout` timeout of 60 seconds, while Grack Git-over-HTTP requests are only bound by Unicorn's timeout which is now set to 1 hour, which should be plenty.

The omnibus package should be updated to no longer use `unicorn['worker_timeout']` for the Unicorn timeout, but to set the `Slowpoke.timeout`.

Connect GitLab buttons doc

The "GitLab buttons in Gmail" documentation was not linked from anywhere else.

Instead of assuming that these docs are not current, or should not be accessible, I've linked to them from doc/integrations/README.md.

If linking is the less desirable approach, please advise.

See merge request !339

Merge branch 'connect_gitlab_buttons_doc' of gitlab.com:perforce/gitlab-ce into connect_gitlab_buttons_doc
