Spell-check code/comments in the Webserver/AVRISP-MKII projects.

Fix up demo documentation device compatibility list to be as general as possible to reduce changes required as Atmel releases more devices within the same USB AVR series.

Remove old OTG demo directory with useless TestApp demo. Add new DualRole directory with new Class Driver powered Mouse dual role demonstration application showing a dual role device using the HID host/device Class drivers.
