Multiplayer Part XI + Mechanics Mods

Attempted to get lightenviro to work correctly for multi, still failing,
what an ass

I reinstated movement interpolation. Without this you could do an
attack, do a 360, and get 360 tracers (noticed this vs admin on multi.
Thought I had it enabled but I didn't). Will modify the variables to
feel comfortable later on

Ground speed is 280 from 400

Attacks requested while current attack animation has 0.5s+ time left,
will be denied
However, if player hits something, that 0.5s+ lock is removed, and can
do another attack immediately

Tapping rightclick will cause player to go /all/ the way to block stance
and then back. Before taping it would start and then stop block
animation immediately.
Issues on replicating this correctly. Am working on it
