added a usb.h and usb.c to cover some of the low level access functions that we can use to build the usb serial port. my sandbox widgets are in main.cpp, look at it then throw it out. I adjusted the stm32f10x_conf.h file to properly NOT include certain st lib files that werent being used, and modified the NVIC init to cope with the bootloader
