Fix makefiles -- the auto-addition of -D switches to each LUFA compile time option was faulty, due to GNUMake becomming confused by the spaces in the USE_STATIC_OPTIONS lines. Make user add in the switches explicitly instead.

Extend USB_GetDeviceConfigDescriptor() routine to require the configuration number within the device to fetch, to add support for multi-configuration devices.

Break device mode class driver interfaces into seperate config and state structs which are then combined, for clarity. Move device mode class driver interfaces back into the device mode class driver headers from the common class headers to make room for host class interfaces.

Better documentation for the MissleLauncher project - add credit to PyLauncher project.

Added new USB_Host_SetDeviceConfiguration() convenience function. Change over Low Level host demos to use the new routine.

Split out common defines/types from class drivers into a seperate common class driver directory.

Make central USB Class driver dispatch headers, used for both device and host modes.

Converted Host mode demos to schedulerless. Fixed host mode broken due to earlier Start-of-frame event experiments.
