Finish Class Driver MouseHost demo. Update HID Host Class driver; boot protocol now works, still need to finish and test report protocol mode.

+ *
+ *  Mouse host demonstration application. This gives a simple reference
+ *  application for implementing a USB Mouse host, for USB mice using
+ *  the standard mouse HID profile.
+ *  
+ *  Mouse movement and button presses are displayed on the board LEDs,
+ *  as well as printed out the serial terminal as formatted dY, dY and
+ *  button status information.
+ *  
+ *  This uses a naive method where the mouse is set to Boot Protocol mode, so
+ *  that the report structure is fixed and known. A better implementation
+ *  uses the HID report parser for correct report data processing across
+ *  all compatible mice with advanced characteristics, as shown in the
+ *  MouseHostWithParser demo application.
+ *  
+ *  Currently only single interface mice are supported.	
+ *
+ *  \section SSec_Options Project Options
