Added FRC SDK libraries
Added two projects for prototype robots. The first is a minimal "basic" robot that doesn't really do anything
but is instead just a simple template.

The second project is a simple robot that uses an arcade-style joystick to drive the robot.
Modified the SunspotFRCSDK directory structure and build to take into account the platform OS and use the appropriate plaform-specific 'preverify' executable.
Updated the sunspotfrcsdk to the latest Dec 30 2013 build.
Changed preverify files to be executable
Corrected warnings in several Ant files.
Added all the JARs and SFX files
Corrected recent change to the build.xml
