There's a similar tooltip for SSH: "Add an SSH key to your profile to pull or push via SSH". These are always shown on-hover, even if the persistent flash above was hidden.

Add headings to signin/signup blocks on signin page.

See #1986

When signup is disabled, the heading for sign in only reads "Sign in", because there is no longer a choice of Existing/New user.

I've moved the OAuth signin options to just below the signin box because it looked odd as a separate box without a heading.

Use gitattribute merge=union to reduce CHANGELOG merge conflicts.

See gitlab/organization#137.

Tested and found working!

@sytse How would you like to address this in [the article](https://about.gitlab.com/2015/02/10/gitlab-reduced-merge-conflicts-by-90-percent-with-changelog-placeholders/)? Simply replace "Thanks ayufan, we'll try this instead." by "Thanks ayufan, we've implemented this instead."?
