- fixed: THe Timidity player didn't close its temporary files and left them

behind because it couldn't delete them.
- added a $MidiDevice option to SNDINFO which can either set the preferred
  MIDI device for a song to Timidity or Windows' standard MIDI device.
  The reason for this: About 80% of my MIDI music collection sounds better
  with Timidity and the other 20% with Windows' standard synth and I'd like
  to be able to use each with the one that sounds better. For MUS files you
  can also force the use of OPL playback.
- added telefrag option to A_SpawnItemEx.
