Use a ChooserTargetService to direct a shared url to a specific host (#572)

* This gives the user a choice of their hosts to share a url to.
* Sadly the youtube app doesn't appear to support this. It wants to
  use some sort of crappy "Message on Youtube" thing rather than using
  standard android stuff (go figure). It does, however, work from a
  chrome browser of the youtube video, or likely any other supported
  share.
