Experience to level

I just build in a level system. You collect the blue tokens as usual, but now your level is calculated too. The level of a player is visible behind his/her name. At the moment you don't realy do anything with it, but it helps to indicate how good a certain player is. I'm also working on userbars that indicate your current level, for example.

Also, there are now moving enemies available. Probably a bit more difficult than the idle ones :)

Currently working on the expansion of the level. I'm making the world higher, because it is way too flat right now.
