Updated a few lights and added text as a mission to unlock T tester

fixed world holes and added lights to cave. Also attempted to fix traitor tester and Traitor teleport rooms. Also added a ladder to one of the vents
EDIT forgot to mention that I changed all the custom textures to default Half Life 2 Textures to prevent people from complaining about not being able to see textures.

increased map size and added more options for traitors
