The Rotations Hotfix

First hotfix. Because I missed some stuff.

I realized that the player's rotation value wasn't constrained in any way, so when interacting with a dialogue object the player would spin really fast to pay attention to it. That's kinda weird, because who even does that?

So now, the player's rotation is wrapped to 360 degrees only. Researchers are still trying to find a way to have the player take the shorter path to look towards a dialogue object. 

Also, particle caching was tweaked a little. Now the associated objects will be cleared correctly and instanced into the level root tree instead of the main tree.
