General Features Update

Furthering the full game, I've implemented 4 levels (So far, More will follow) as well as a level selector, It also saves whether or not you've finished the tutorial, as well as which was the last level you played.

However, I've also implemented a way to move the Laser Emitter. (So that way I can do it for my levels). You can have a maximum of one Start. You cannot preview your level without both a Start and at least one Finish.

At the moment I have no plans to allow the Laser Emitter to be placed anywhere, but if that's something you guys want, I can implement it with only a little hassle.

If there is any levels that you made that you wish in the final game, feel free to screen-shot them (From above)
