Footsteps Update

Hello @everyone WarDust got an update!

changelog (seems small, but it was a big job) :

-Reworked footstep audio system (not finished yet)

Footstep sounds will change based on different surfaces:
"Water"
- "wood"
- "dirt"
- "concrete" (generic sound, kind of universal)
- "sand" (can be used also for snow)
- "metal"
and last one is Default if no other surface is detected.

-Couple small fixes here and there
