Implemented friendly notes and octaves (ie: "A5" instead of "97")

* "MIDI_NOTES" defines the chromatic scale (C through B)
* "MIDI_OCTAVES" defines the standard midi octave range (-2 through 8)
* the code now converts the note number in to note, note name and octave data
* new jump labels based on note names, such as "MidiNoteOnA5" and MidiNoteOnA"
* new jump labels for control changes, such as "MidiControlChange1"
Small tweak to summary example in readme
