vertical grid in graphic editor, zoom keyboard in piano roll

[jeffsaun]

A couple minor suggestions that I think would make the graphic MIDI editor a little easier to use:

vertical reference lines for subdivision of time smaller than measures - sixteenth notes, or customizable.

option to zoom the vertical keyboard (make horizontal lines wider or more closely spaced).

...... Poof!

Option-click the zoom icons and piano is scaled vertically.... magically!
