Fix detection of invalid music drivers specified via command line.
Along with it documented that "0" is a special device handle
for the invalid device. Now getDeviceHandle returns 0, when
the identified device could not be found.
Also getMusicType now returns MT_INVALID (newly introduced),
when a non existing device was specified.
