firmware: add bootloader update "app"

Browse Source 
This bl updater can be flashed as app and will update the bootloader and
then
delete itself before resetting the sam3, so the device will end up in
the newly
updated dfu bootloader afterwards, without having to press the
bootloader button
or requring any other manual interaction, ready to receive a new
application image.

Building the blupdater requires a previously built dfu-flash bootloader
bin file that
will then be embedded into the app during building.
