Fixes longstanding issues with low nb_update_frequency.

Current list of fixes

• Infected stucking at corners
• Commons pushing themselves out of the way
• Climb up ledge activity stucking

ConVars

PHP Code:

// 0 - Use original function, 1 - Use extension implementation with fix, 2 - Use extension implementation without fix, 3 - Neither of calls
z_resolve_collision "1"

// Listen server only
// 0 - Disable collision overlay, 1 - Enable collision overlay, 2 - Enable clean collision overlay (works only for 1 common but smoother)
z_resolve_collision_debug "0"

// 0 - Use original function, 1 - Use extension implementation
z_resolve_zombie_climb_up_ledge "1"

// 0 - Disable debug, 1 - Enable debug
z_resolve_zombie_climb_up_ledge_debug "0"

// 0 - Use original function; 1 - Use extension implementation
z_resolve_zombie_collision "1"

// Multiplier of commons collision force
z_resolve_zombie_collision_multiplier "1.0"

// Automatically manages power of collision between commons
z_resolve_zombie_collision_auto_multiplier "1" 


For developers?

Spoiler

If you are curious what was the problem then keep reading.
You probably know about problem where with high tickrate and low nb_update_frequency value, common infected starts getting stuck at every possible corner.
It's because due to lower interval between updates common infected moves less distance and that starts triggering early return for collision check without a chance to escape collision resolution or try to solve it (See code references).
Yep that's it.

First collision check early return
Second collision check early return

Why thread has "Experimental" in parentheses?
Because even tho I removed those 2 checks and this fixed the problem I still have no idea why someone added them and what could potentially break without them.

Brilliant stuff

absolutely masterpiece, it is so annonying that witch get stuck every time when server 100 tickrate.
Finally get rid of

MSVC optimization breaks something so current windows build compiled without it.

witch still gets stuck
server tick: 96
nb_update_frequency: 0.0

Extension doesn't fix every possible stuck situations.
Only those that were affected by ResolveCollision early return but thanks for report, I will try to fix it.

One of hundreds of tests

try lower z_resolve_zombie_collision_multiplier value?
