Extend the butterfly code to fully support AVR109 boot loaders. Notable

Browse Source 
changes to butterfly.c include:

. do not exit for unsupported devices but return -1 from the init function
  instead; that way the -F option can be used to continue anyway

. honor the -b option as arbitrary bootloaders could be implemented with
  any baud rate, not just the fixed 19200 Bd used by the butterfly

. implement functionality to read the fuse and lock bits, and write the
  (boot) lock bits, resp.

. fix the signature byte order

The remaining files document the new functionality.
