4 Legion animation issues

Tatariu

1. The Legion's knife snaps into position when starting a Frenzy, instead of smoothly moving into place.
2. The Legion's hands both snap into position when ending a Frenzy, instead of smoothly moving into place.
3. While in Frenzy, falling from any height does not play the appropriate animation from first person to reflect the change in motion/direction.
4. The Legion's knife does not pivot up/down when looking up or down, and instead is always held in the same position.
