QMK DFU bootloader generation (#2009)

* adds :bootloader target * update planck and preonic revisions * remove references to .h files for planck * update preonic keymap * only add keyboard.h files that exist * add production target * hook things up with the new lufa variables * update rules for planck/preonic * back backlight key turn of status led when pressed * add manufacturer/product strings to bootloader
