Merge pull request #7 from CJoriginal/master

MCAPP Version 0.6.3
MCAPP 0.6.4

Merged file importer/exporter properly.
MCAPP 0.6.5

Fixed miscredit.
MCAPP 0.7

Shavarsh's merge
MCAPP 0.7.1

- Key signature backend interface done - no implementation yet.
- Changed how note pitches work - the Note object stores the _vertical
index of the note_ now, NOT the number of semitones above/below middle
C. This is so it can be used as a lookup by the key signature.
- Moved the grid-to-pitch table into Globals - although it may seem that
it should probably exist in Player, it will be needed in the future for
demoing notes.

Signatures (accidentals) implementation.

MCAPP 0.7.3???

I don't even know what version we're on now.
- Key signatures working (partially - any signature with a root like A#,
C#, D#, etc. cannot work yet). See FB group for exact details.
