microchip hid usb loader

ported over the microchip one too.

started a wiki page.

I ported both the older version of the HID bootloader and the newer one, they're compatible formats

Note about ORG'ing your app to 0x1800 though (i'll try to reduce the size of the bootloader so we can org at 0x1400 )
