PROTOTYPE Update 5 - Zip Zoom to the Moon!

This is part one of many of the parkour revamp. Bugs abound.

+ added an actual kick off the wall during wallkick
    -> who'd have thought that a system called "wallkicking" would feature kicking off of walls?
+ buffed wallkick speed bonus
    -> now you'll go a bit faster forward when wallkicking
+ increased FOV pullback when sprinting and wallkicking
    -> now you can see for fecking miles...
+ implemented boosting system
    -> only useable by wallkicking while sprinting; soon to include long jumps off ledges...
- nerfed wallkick jump height
    -> it was not only possible but really easy to jump off the map into an infinite gray purgatory
= KNOWN ISSUE: movement drifting
    -> if you boost too many times on only one side, you start to drift to that side when moving
    -> it gets worse and worse the more you repeatedly boost to the same side
    -> cause currently unknown; will be fixed later
= KNOWN ISSUE: Mental stats only increase Tier every OTHER level?
    -> I have no idea why, since Tier should calculate using PHYS and MENT at the same time
    -> I didn't even look into this yet; it will be fixed next update
    -> substats and MP calculations don't appear to be affected at all
+ added a banger of a Drawfee reference
    -> im merobiba
