Le Fromage

Let's keep this short:

• Small changes to levels 3, 29, 37, 82, 83, 84, 85 to prevent (or disincentivize) unintended solutions. 
• Fixed uv-mapping issue in level 28. 
• A small force is added to character-controller, if it is stuck in a frame with gravity pointing towards the frame on both sides. I hesitated for quite some time to add something like this, because I consider it important to have consistent rules (or consistent physics in this case). However, only a small force is added under very specific circumstances. So most players probably won't even notice, but it might prevent an annoying reset here or there.
