Subject: 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
