Optimized Mettaton opera scene. The cherry petals were killing the frame rate, so I've added something that deletes them when they go off-screen. Surprisingly, there wasn't anything like that in the original Undertale either, due to what seems to be an oversight...

Anyway, it's a small patch. I was holding off on posting it until I gathered a couple more bugs, but so far, nothing else seems to have popped up, so here it is. In it's tiny glory.
