New Prototypes and Updates to Tw2AnimationController
New Prototypes and Updates to Tw2AnimationController

- Added support for pending commands that have no arguments `_DoRebuildCachedData` @prototype
- Added `GetAnimation` @prototype which returns a loaded `Tw2Animation` by it's name
- Added `ResetAnimation` @prototype which resets a loaded `Tw2Animation` by it's name
- Added `PlayAnimationFrom` @prototype which plays a loaded `Tw2Animation` from a specific time. Didn't update the existing `PlayAnimation` as it could break people's existing code
- Updated `StopAnimation` @prototype so that it can also take a list of `Tw2Animation`s
- Updated `StopAllAnimations` @prototype so that it can now be called before any animations have been loaded, and will stop them when they have
- Added `StopAllAnimationsExcept` @prototype that stops all `Tw2Animation`s except those that are supplied by name in an array
