Mobile Friendliness

With this update, I added mobile support, I've fixed the spawners not working properly, and I've made the lights' intensities fade instead of snap.

I hadn't realized that the spawners weren't quitting after spawning all it was supposed to spawn. I almost completely redid how spawners work while trying to figure out why it wasn't working. I made the times between waves depend on how many bugs were spawned. I also completely redid how the lights work because I couldn't figure out why they weren't fading instead of snapping. It ended up also being hidden in the spawner code. I fixed that as well, so now it looks a bit better.

This was the first project I've messed with lights in without writing them from scratch, which I've only done once, during a tutorial.

Still don't have any textures on the walls, because we haven't tried to figure out how to get a shader to show vertex colors.
