Make Clip+ bootloader build

Browse source 
Now making the Fuzev2 bootloader build should be pretty easy

TODO:
    - write button driver (FlynDice found all buttons already)
    - find button light
    - decide if lcd-ssd1303.c must be modified for Clip+ using SSP or forked
    - check if backlight code works (I copied Clipv2 code)
