Relative links in project README should point to default branch, not master

Relative links in the README shown on a project's main page currently always point to the "master" branch.  This is a particularly obvious problem for projects that have no "master" branch, since the link points to a non-existent file.

This patch changes the relative links to instead point to the default branch.

Resolves #2707, #1134, #1852

to the default branch, not to master

refactor login as to be impersonation with better login/logout

Modifies the existing "login as" feature to be called impersonation.

This also adds:

* Application keep track of who is impersonating the user so they can revert back to the original user without having to log out.
* Stores the user profile via `HTTP_REFERER` so you get redirected back to the person you have impersonated once you stop.

Expose builds feature

Expose builds feature in project settings (as feature).

Enable it by default for a new projects.

I deliberately named it builds instead of CI, because we actualy allow to run tests using infrastructure built-in GitLab. I'm free to change it.

If we are ok, I'll add feature tests for it.

Add missing "omniauth" prefix to option in docs

This MR is specifically a fix for #3319. I wanted to make my first contribution to GitLab, so I picked a simple one!

This changes the omniauth documentation for the `block_auto_created_users` option to `omniauth_block_auto_created_users`.

Thanks
