Changed Still Image Host class driver to auto-fill TransactionID element of sent headers depending on the current session state.
CDC based demos and project now work under 64 bit versions of Windows (thanks to Ronny Hanson, Thomas Bleeker).
The Benito Programmer project now has its own unique VID/PID pair allocated from the Atmel donated LUFA VID/PID pool.
