Code wise changes: Implementing the intended way of using the new ApplyMod system to minimize potential side effects for other mods.

Implementation of a basic structure collision detection system to vastly improve the accuracy of the effect position. It will however ignore devices and always consider door are closed.

fixed the buzzsaw interaction with brittle materials (now deals appropriate damadges to them).
