+ Refactor input handling from browser window code into content

  handlers.
+ Disentangle all box tree manipulation from browser window
  code and put it where it belongs.
+ Move other content specific and other irrelevant code from
  browser window handling to appropriate places.
+ Put mouse state enum in new mouse header, since it's not just
  used by browser window code, and it is used by treeview
  windows on the treeview branch.
