- Add OpenPICC register definition (and USB command handling)

- Add automatic generation of include/compile.h with svn revision and compiletime
- Add openpcd_compile_version structure to obtain version via USB
- Move LED commands into new CMD_CLS_GENERIC family
- Update TODO
- Add support for large (2048 byte) request contexts in addition to 64byte
- Shrink req_ctx size by collapsing rx and tx buffer into one
- move definition of DFU_API_LOCATION to header file
- Implement large req_ctx aware USB transmit / refill routines
- Implement TX refilling for IRQ Endpoint
- Print version information at startup time
- move some generic req_ctx processing into usb_handler.c
- Some further work on DFU (still not finished)
- Only use '-Os' for DFU, use '-O2' for application code
