Fixed a bug where the MIDI mode display wasn't
being displayed properly at launch.
It now asks you if you want to save befre quitting.
Put a new item in the Options menu so that you
can disable pressure feedback on pads to reduce
CPU usage.
Added an 'Update Firmware Utility' item to
the hardware menu to allow the user to upload
custom firmware files to the sphere. This involved
rearranging the firmware updating code.
