* Reworked closing a page programatically. BWebPage no longer sends a plain

B_QUIT_REQUESTED, instead BWebWindow has a new hook and derived classes can
  implement it.
* Some refactoring in BrowserWindow to move code from MessageReceived into
  separate methods for easier debugging and cleaner code.
