Added support to the HID parser for extended USAGE items that contain the usage page as well as the usage index.
Removed the HID_IOF_NON_VOLATILE and HID_IOF_VOLATILE flags from HID INPUT items where the flag is invalid. Changed over HID OUTPUT items to use HID_IOF_NON_VOLATILE.
Change over MagStripe project to use HID_DESCRIPTOR_KEYBOARD() for its HID report. Change over MouseHostDevice demo to use HID_DESCRIPTOR_MOUSE() for its HID report.
Fixed ReportID not being removed from the feature/out report data array in the HID class driver when Report IDs are used.
Added new MAX() and MIN() convenience macros.
Rename LowLevel.c/.h to USBController.c/.h.
Remove dependancies on the complete <avr/io.h> header in the HighLevel USB driver directory, to ensure less work is required in later (possible) ports.
