Bunch of match preview tweaks:

. Makes MatchPreview owned by Browser rather than each TabContents.
. Makes MatchPreview dismiss when the omnibox closes.
. Supports the ability to send script to the page rather than
  reloading on every keystroke.
. Supports receiving results from the page that drives the suggest
  text in the omnbox.
