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

Added support for pose parameters, including Dupe support, only for Animatable props though
"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
* "Make Animatable" no longer usable on brush entities and doesn't error with bad entities

* Removed experimental feature that unintentionally made it onto workshop

* Fixed "Make Animatable" not working well on prop_effects
* Improved the physics of animatable props and their visualization, latter of which can be disabled with the Glows option on the tool
