Lock entities/physical bones to nonphysical bones

[vlazed]

This shall extend the current bone locking and constrained entity locking features for nonphysical bones

I was able to accomplish this with the Ragdoll Weld tool. This method uses GetBonePosition

However, this method, which runs on the server, updates on a lower rate. In other words, objects constrained to a nonphysical bones will lag behind. I could try forcing the bones to update its server position every tick I'll look into using GetBoneMatrix to see if this helps reduce the lag

Alternatively, I can run a chain of LocalToWorld functions from the physical vone to the nonphysical bone. While it may update positions quickly, it also increases server calculations--this is a highlight for #40, which calls for clientside calculations
