integrated serial mouse drivers as a feature into the firmware architecture
* can be enabled by defining Makefile macro SERIAL_MOUSE_MICROSOFT_ENABLE or SERIAL_MOUSE_MOUSESYSTEMS_ENABLE. * Serial implementation can be chosen via SERIAL_MOUSE_USE_SOFT and SERIAL_MOUSE_USE_UART macros * UART configuration still has to be done in config.h: I added working clauses for both mouse protocols to ps2_usb's config.h
