New make environment for new bootloader

Compatible with old bootloader. Adds an additional section with a copy
of the interrupt vector table to the end of the image. This is needed by
the new bootloader and should be ok for the old bootloader.

Note that for this to work, everybody needs python installed with
the IntelHex python package. On Linux this can be achieved with

pip install IntelHex
