Misc dev

[Vauff]

• Fixed a compiler warning/optimized code in player physics shuffle
• Silenced string conversion warnings in cases where non-numeric input is expected
• Fixed bugged active weapon if a grenade was thrown right before infection
• Fixed knife skin not always matching loadout if different knives were equipped for each team
• Fixed revived humans not having armour, obeys mp_free_armor
• Added re-strip on revives, prevents ZM items lingering
• Fixed zombie regen clamping health values above max health (fixes paramina ZM item HP, still recommended to set max_health to enable higher regen)
• Stopped transmitting flashlights in spec, this was causing random rare "missing client entity" client crashes since some CS2 update
• Added matchmaking bin to available gamedata bins
• Switched to smart pointers for ZR weapon configs, should no longer leak memory
• Added possible workaround for CS2 randomly spawning players with mega-velocity (example), unknown if it works
• Fixed a crash with @aim targeting
• Updated extend tracking, so total extend count is now shown in !extendsleft
• Removed !addextend, since it's redundant with !adminve existing (or adjusting cs2f_extends)
