[Cluso99] Feature: Unscrambled ROM

Based on this forum post: http://forums.parallax.com/showthread.php/156866-Question-for-Chip-re-ROM-code?p=1287017&viewfull=1#post1287017 by Ray Rodrick (Cluso99)

Purpose: reveals the binary code of the ROM programs in the hub, which was previously closed-source but not anymore (see ROM_Sources directory)
Benefits: saves a few LEs that are normally used to do the descrambling
Incompatibilities: Changes the ROM data from the original Propeller
Activation: define the ENABLE_UNSCRAMBLED_ROM macro.

Thanks Ray!
