Fixed KillMoves not killing some NPCs like Striders

bsmod_kick delay now properly works with decimals.

Tweaked something

Fixed being able to KillMove team members (for reals this time)

Tweaked default KillMoves to not interfere with custom ones

- Added custom KillMove support, refer to https://psteamcommunity.yuanyoumao.com/workshop/filedetails/discussion/2106330193/3108015514310459664/ for more info

- Improved KillMove animations to look better in thirdperson (no more crappy t-pose)

- Fixed a script error when undoing a KillMove target right after initiating one
- Fixed KillMove targets persisting if they get undone during one

Fixed KillMoving changing your view when it's somewhere else such as a camera

Fixed player colour, bodygroups, etc. not showing when kicking.

- Fixed killmoves looking a bit snappy at the start of their animations
- Fixed killmoved models sometimes leaving behind shadows
- Fixed punch SWEP playing the draw animation after killmoves
