GGrewve Style Switching

I had a rather unexpected success today in implementing the "style pool" engine in GGrewve. It took far less coding than I had imagined and worked almost flawlessly on the very first try. There's little more that one can ask for!

The excellent style switching made the whole composition sound even more coherent and varying than it already did. GGrewve now pays more attention to intensity than any other plugin, actually changing its playing style based on the value. This, ideally, is how each plugin should act. GGrewve is really a role-model for the other plugins and, once again, I am extremely proud of how well it performs.
