Texture fix test

Changed breakable window texture to something better.

Removed ladder at Rebel base and changed water/window textures to something more shared.

Reduced Rebel base structure's height enough to make it easier to climb up to the roof.

Included textures with map in an attempt to fix issue with black textures.

Fixed Rebel generator missing the appropriate targetname.

Extended both base areas down to fix props not being physgunnable due to them being outside of the base area.

Fixed up ladder and added "Observation" sign to Rebel base to indicate the ladder's position.

More Rebel base adjustments.
