* Introduced a monitor_info structure and means to let it be filled by the

Browse Source 
accelerant (or the app_server via EDID info). It's still experimental
  API, and opinions are welcome.
* Moved BPrivateScreen into the BPrivate namespace.
* Rewrote Screen.h.
* Introduced a BScreen::GetMonitorInfo() method, and implemented it in the
  app server as well (ie. AS_GET_MONITOR_INFO).
