* [bug #9] Fixed for a LSCP command syntax convention
  consistency, regarding the enumeration of available
  sampler engines, Audio and MIDI drivers; this has
  affected the semantics of the following commands:
    GET AVAILABLE_ENGINES
    GET AVAILABLE_AUDIO_DRIVERS
    GET AVAILABLE_MIDI_DRIVERS
  which are now returning an integer count of engines
  and drivers, respectively, while the following
  new commands are now being introduced:
    LIST AVAILABLE_ENGINES
    LIST AVAILABLE_AUDIO_DRIVERS
    LIST AVAILABLE_MIDI_DRIVERS
  taking on the previous functionality, returning
  a comma separated list of names.

* LinuxSampler version bumped to 0.3.1.
