The original code was shocking once I started reviewing it, and even after heavy editing I'm still not happy with it, but at least it works more like it was supposed to. Needs more cleaning up to make it clearer and probably safer. Also, presets can now contain langage packs and they'll be used. The image gallery is an example.
