Add support for ragdoll charms

[StellarSt0rm]

It would be very useful to have a new type of charm, att.CharmRagdoll. This would allow for more dynamic charms.

For example, you could the breen player model (models/player/breen.mdl), and instead of T-Posing it would have ragdoll physics.

I dont know if this would even work, but but it would be amazing.
