* Added playerclips on that pond from outside (this was actually for those stupid bots)
* Removed trigger_hurts on those radioactive ponds because they're now useless with the playerclip walls
* Added playerclips on the armor stairs
* Added ending music and fade in after completing Wave 12
* Redo barricade health to 500 because for some reason the game ignores custom barricade health values
* Fixed zombie jump node hints (I guess)
* Removed crystals from windows
* Added a new teleport zone
* Added more spawnpoints and crates
* Removed lifts, replaced them as simple stairs instead
* Removed inexistent func_nobuild brush entities

* Patched that superjumping bug which occurs while jumping seconds before the outside elevators descends (it actually teleports you back)

* Increased safezone barricade durability to 900
* Added more spawnpoints
