WIP hosted port to the Surfans F28

* Only bootloader builds
 * Plugins disabled
 * No keymaps to anything else
 * No simulator
 * Touchscreen not wired up yet
 * Audio still untested

Bugs:

 * rotary encoder does nothing in bootloader
   (might be bootloader bug, might be something else)

Other stuff pulled in:

 * Unify all of the (identical!) hibyos makefiles
 * Rename the "bootloader" to more generic name
