Animation specific limb constant angles

[TheNinjaScout]

Adds a new character animation property "LimbConstantAngles" which is formatted like this: "limbID: constantangle;constanttorque, limbID2: constantangle2;constanttorque2, ..."

This allows specific limbs to assume certain angles with certain torque depending on the currently selected animation, allowing more control over how a character's limbs are posed, especially for non humanoid ones

Limb-defined constantangles and constanttorques will be used if there aren't any animation specific ones for that limb

Constanttorque is no longer applied to limbs if the character is stunned / unconscious (could add a way to circumvent this later, maybe with a limb specific boolean property and/or even an animation-wide one to allow things like custom death poses by swapping animation set after death, but not sure how worth it it is)
