Fixed Web Version (?) - New World Generation Testing

Web Fix:

I have updated the web version with hopefully a fix for people who were getting stutters and crashes. I've also added a quick initialization screen that loads most things at once at startup to keep stutters from happening the first time something loads in.

World Generation: (only in the web version for now).

I also changed how levels are generated. This is sort of an experiment, but I was noticing a few people were just falling forever in the infinite world. I've now changed it to be a closed-in arena  I think this plays a bit better. 

I believe this will help people from running into newly generated platforms when moving too quickly, and I think it will help people get more familiar with the controls by getting used to a certain area. The border is really bland right now, but that will change soon as doing it this way also lets me add more background graphics easily.

New Look:

I've also added a test for changing the look of the world. It now will choose between 2 different "locations". If you press control on your keyboard, it'll generate a new level on the fly. This is just for this is test build. I figured it would give people a chance to check it out and let me know what they think.
