MinoClockSource: new uppqn() accessor
MinoAnimation: remove deprecated functions
Minotor: introduces object creation (pre-note) concept
MinoInstrumentedAnimation: new MinoAnimation subclass that will support notes
MainWindow: clean unused functions
ConfigDialog: starts on first tab
MinoAnimationGroup: always set _alive and item visibility together
MidiInterface: move open(QString) as protected method
MidiInterface: support virtual port creation using external RtMidi

This patch is a bit hacky and need to be cleaned: external RtMidi pointer should not be used but handled internally.
MidiMapper: comment qDebug() in noteChanged()
Midi: code indentation
Midi: create a virtual MIDI In port

Minotor does now expose a virtual MIDI in interface that can be used to drive Minotor using applications (LMMS, KMidiMon, etc.)

Note: this implementation can be improved ("Minotor" is hard coded, virtual port create could be generic, etc.)
MinoInstrumentedAnimation: first draft of note implementation

To be improved: only applicable to MinaFallingObject right now, no channel filter, notes does not provide right color, etc.
