Added keywords for new libraries, rearranged and modified Due and USB examples

Renamed Leonardo Only examples folder to USB. Modified keyboard and
Mouse examples to indicate Due compatibility.

Minor modifications to Due examples to conform with existing example
sketches.

Added keywords to for Audio, Scheduer, and USBHost libraries.
