Added Omar's new CanTalonSRX code.

I also updated the C++ and Java code some. For C++, this meant making it
compile and adding in the framework for the closed-loop control of the
motor. For Java, I updated the JNI bindings with SWIG and created an
GetTemperature accessor function to demonstrate how to use the accessors
because swig does funny stuff with pass-by-reference functions.

 integrate the swig stuff into the build system. For now, all the generated JNI
 bindings are checked into git, so that it should work until someone goes and updates ctre/CanTalonSRX.*

+In order for this to work, I had to change the CanTalonSRX constructor to take a int deviceNumber instead of a uint8_t.
