Algodoo

This was definitely much harder to make than the previous sieges, but it's finally done.
Although there are a few bugs but are mostly visual.

I also changed how to make the GUI invisible. Now you remove it by pressing shift while the simulation is running.
Just remember to change it back before you leave.
