Global nav

• For gitlab-com&21 (closed)
• Closes https://gitlab.com/gitlab-com/gitlab-docs/issues/169
• Clean-up after https://gitlab.com/gitlab-com/gitlab-docs/merge_requests/356 - see all history there!

REVIEW APP: http://global-nav.178.62.207.141.xip.io/ce/README.html

MVC:

• Create the global nav
• Make it work on mobile (hidden on mobile ATM)
• BE review (just double check)
• FE review

FOR FE review:

• When we scroll down the nav, when it finishes scrolling, the page starts scrolling the content. Fix this to simply when the nav stops scrolling, just stop right there.
• Try to fix buggy ToC toggle (note that it's displayed only on mobile):
  • the first click doesn't collapse it
  • on the next clicks, there's a brief (weird) pause when the div is collapsing
