*Update*
I added multiple sbsp support for sp maps. It covers all the sbsps now, but it seems that there are some more coll faces we are missing smoewhere. I tested on outskirts and about 80% - 90% of the surfaces are climable.
Thanks Aton to:
DarkMetal for the GUI
LuxuriousMeat for Betaing.
Shade45 for the actual discovery
