Subject: First integration of the Arduino code in Processing 5503:
 PreProcessor and Compiler have been integrated with changes to the Sketch.
 Compilation still has problems (Thread error on success, and can't handle
 non-pde files in a sketch). Modified the Mac OS X make.sh to copy the
 hardware, avr tools, and example over. Removing some of the antlr stuff.
 Disabling the Commander (command-line execution) for now. Added Library,
 LibraryManager, and Target. Added support for prefixed preferences (e.g. for
 boards and programmers).
