Added patch originally written by Ingo Weinhold:

- extended libdebug.so functionality to be able to get stack frames,
  current instruction pointer, etc.
- changed the debug_server to be able to run as a simple BLooper - this
  saves some trouble when the app_server dies
- the debug_server now prints out a stack crawl for the crashed team
  (without symbols, though - for that data to be helpful you should
  have a look at the loaded images (ie. where they start))
- the debug_server now also prints the team name when it kills it
