MIDIMonster v0.3

"The last release of the decade"
This release contains bugfixes to the winmidi, jack, maweb, evdev and sacn backends,
as well as the new 'local' option for descriptors of the sacn backend.
It updates several example configurations and introduces a layering demonstration.
This release introduces command-line argument parsing, initially by providing a
'-v' parameter for querying the binary version.
Due to internal API changes, backends built for previous releases are incompatible with
this release.
