* src/Sampler.cpp: fixed 3 stupid but fatal bugs that left in the rush (in
  method SamplerChannels(), CreateAudioOutputDevice() and
  CreateMidiInputDevice())
* src/network/lscpserver.cpp: implemented LSCP command
  'SET CHANNEL MIDI_INPUT_CHANNEL'
* src/Sampler.h: moved enums 'audio_output_type_t', 'midi_input_type_t'
  and 'engine_type_t' into the respective base classes
  ('AudioOutputDevice', 'MidiInputDevice', 'Engine')
