* lib/PandoraFMS/Server.pm: Enabled thread status detection when
available.
* lib/PandoraFMS/Core.pm: Fixed module status calculation. Moved and
rewrote the old pandora_ping* functions. Small aesthetic fixes.
* lib/PandoraFMS/ReconServer.pm, lib/PandoraFMS/NetworkServer.pm: Use
the new pandora_ping* functions. The old functions were not thread
safe and had to lock.
* bin/pandora_server: Properly shutdown on error.
