Completely rewrote the firmware to be simpler, more understandable, and faster
Revert "Added preliminary build script converted to bash for more portability...don't know if it will be used over the perl one yet"

This addition was unnecessary, since Perl is distributed on most mainstream operating systems.

This reverts commit db65ec22075db1f4dc6a65738ff55720bb604b49.
Removed firmware with stepper motor, as it will never be used again
Renamed robot firmware to be the only firmware
Merged Chris Ayala's patch for the Mac OS X installer script
Changed the installation script directory from RXTXcomm_INSTALL to INSTALL.  Updated README reference to it as well.
Updated the examples to be up-to-date with the new API version
Added the option to stop the robot from resetting the motors when the connection closes
Added the ability to override input validation....this can be used by groups who buy, for example, a 360 degree servo
