fix(ui): match top bar to doc.owncloud.com (title in, external links out) (#32)

Two changes to the navbar, mirroring doc.owncloud.com:

- Add the site title next to the logo via <span class="navbar-title">, with
  supporting CSS (the stock default UI ships no .navbar-title rule): white
  text, a subtle left divider, hidden below 768.5px so it never crowds the
  logo/search on narrow screens.
- Remove the external "ownCloud.com" / "Support" links from the top bar. They
  duplicate links now present in the branded footer. With them gone the
  navbar-burger had nothing to fold, so it is removed too and navbar-end left
  empty -- exactly as doc.owncloud.com does it.

All in ui/supplemental/ (header-content.hbs, owncloud.css); not synced.
