Small fix related to rb655_easy_animation_nobbox_sv

Added rb655_easy_animation_nobbox_sv convar - hides the white box around animatable models for everyone on the sevrer

"Make Animatable" now also copies entity's animation ("sequence") and cycle ("animation frame") as well as the pose parameters
Animatable prop bounding box only shows up when Toolgun or Physics Gun is in the player's hands
Animatable props now have 2 new features, accessible from the Context Menu (Hold C)
* Ragdoll/gib on damage
* Animate movement pose parameters

* Fixed Animatable prop bounding box not rotating properly
