Make sure the protocol handler files are included in the Doxygen documentation of the AVRISP project.

Document the PDI programming routines implemented so far in the AVRISP project. Add ability to selectively disable ISP programming support in addition to the existing ability to disable PDI programming support.

Move AVRISP Programmer project to a new Unfinished subdirectory of Project while it is under development.

Added new Endpoint_SetEndpointDirection() macro to set the current endpoint direction for bidirectional endpoints.

Renamed internal USB_INT_ENDPOINT_SETUP macro to USB_INT_RXSTPI to fit in with the rest of the interrupt vector macros.

Change Doxygen configuration files to not produce 4096 directories for the documentation files -- the LUFA components do not generate enough documentation files to justify the large performance hit of creating so many directories.

Fix missing Doxygen documentation in the Class Driver Mass Storage Device demo.

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

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

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.
