Slightly revise the handling of BGEE

 -Use a different file for detection
 -Try to load the tlk in lang/ in preference to the tlk in rootdir.
  The former does not exist in the original games, but the latter may
  exist in BGEE.
Merge branch 'master' into devel
Fix a bug with resource loading from BCS
Overhaul the starting of inferior processes

- Use ProcessBuilder instead of Runtime.exec()
- Open URLs with java.awt.Desktop
- Disallow playback of MVE files on platforms other than Windows (since
  that is all the implementation covers)
