1. Fixed the ArbotixFirmata sketch to comment out references to the INPUT_PULLUP
2. Modified the openFrameworksArduino.lua and x64 project files to use BOOST_ROOT and OSG_ROOT env variables now instead of assuming they are in 3rdParty folder.
3. Added a new stop command for the motor.
4. Modified the swing/stance phase to move more slowly. If you have a smaller power supply (1A) and a default dynamixel then that power supply cannot handle all 3 motors moving at max speed at the same time.
