Oops: Really disable building of Projects/Host/ClassDriver directory in the Projects/Host/ makefile. 

Add more skeleton functions and definitions to the Mass Storage Host mode Class driver.

Made Endpoint_Write_DWord_* functions echo the structure of the matching Endpoint routines for clarity.

* - Added return values to the CDC and MIDI class driver transmit functions
* - Added extra masks to the SPI driver, changed SPI_Init() so that the clock polarity and sample modes can be set
* - Optimized Endpoint_Read_Word_* and Pipe_Read_Word_* macros to reduce compiled size
* - Added non-null function parameter pointer restrictions to USB Class drivers to improve user code reliability
