GCN Plugin New - Should be the only controller plugin.

We don't need multiple controller plugins. Not for what the others offer. We can leave the plugin ability, but I see no reason to keep the other two plugins in the package. All the Emulator needs is GCN Plugin New.

I'm working on the emulated wiimote plugin using the same input system and gui as gcpadnew. Once it's completed and as good as the current wiimote plugin, I think the old plugins will eventually be removed.
