Updating to Use JRuby-1.7.4

I've recently updated ruby-processing to use jruby-1.7.4, and for Mac and Windows users, it has been updated to use processing-2.0 (untested, you might be the guinea-pig). Seems to work OK linux. I am not all interested in updating ruby-processing processing-1.5.1 to use jruby-1.7.4 so unless someone volunteers the next release of ruby-processing will be a huge leap (if you've got a crappy graphics card the experience may not be so wonderful!!!!). Processing 2.0 uses opengl2 for P2D and P3D rendering so if you've got a reasonable graphics card there are decent improvements to be had including easy access to glsl shaders and FBO (buffered on graphics card).
