Gaps 1.0.1 - Max fret option and minor bugfixes

Added a new option in the settings menu to set the number of frets on your guitar, so that Gaps will now only generate intervals, degrees and melodies within those frets.
Fixed a bug where the microphone would pick up the audio from the speakers on the first question of a redo of a degrees exercise.
Fixed a bug where the 'minor' setting on the melodies exercise would contain the wrong intervals. More info/support at gapsguitar.com
