SWIG adopted for native interface generation!

I have adopted SWIG (Simplified Wrapper and Interface Generator) to generate the mapping layer between C/C++ and Java!

The means that all the native code used to wrap the SDL Library is automatically generated from simple swig (.i) interface files!

This is already working for the video module and I have just confirmed that it works with the Event module as well.

Excellent news as it simplifies the job to bind the SDL to Java. It should be possible to have a release up and available within weeks.
