Added new USE_INTERNAL_SERIAL define for using the unique serial numbers in some AVR models as the USB device's serial number, added NO_INTERNAL_SERIAL compile time option to turn off new serial number reading code. Updated Mass Storage and CDC based demos to use the new device serial number if the device it is compiled for supports it.

Move new Class Driver powered demos to a new ClassDriver subdirectory, re-add old low level demos to a LowLevel subdirectory.

Deleted StdDescriptors.c, renamed USB_GetDescriptor() to CALLBACK_USB_GetDescriptor, moved ConfigDescriptor.c/.h from the LUFA/Drivers/USB/Class/ directory to LUFA/Drivers/USB/HighLevel/ in preperation for the new USB class APIs.

Changed PIPE_CONTROLPIPE_DEFAULT_SIZE from 8 to 64 to try to prevent problems with faulty devices which do not respect the given wLength value when reading in the device descriptor.

Further documentation improvements - removed file view from the main library documentation, replaced file references in the documentation with group references.

Applied STATIC_ENDPOINT_CONFIGURATION and FIXED_CONTROL_SIZE tokens to all Device mode demos to reduce binary size.

Changed over all deprecated GCC structure tag initializers to the standardized C99 format (thanks to Mike Alexander).

All comments in the library, bootloaders, demos and projects have now been spell-checked and spelling mistakes/typos corrected.

Seperated out OTG, Device and Host mode demos into seperate folders for clarity. Adjusted makefiles so that the path to the LUFA library can be set in one place.
