Removed new Start of Frame event from the library; performance suffered far too much and it was only useful in one of the standard classes (HID). Altered HID demos to use the previous method of tracking millisecond periods via a hardware timer rather than the SOF events.

Fixed MIDI class driver blocking on unread events to the host.
