Grandhill a1e

Barring any sort of exploit or error, this should be the last version before playtesting.

Changelog:

Changed out the fence for an actual wall at the lower exit of Blu's second spawn.

Added a fence to the cliffs within eyesight of point B.

Added a one-way door to the mining hut building when exiting towards point C.

Sealed up the vantage point overlooking point B (might return in version A2 with a one-way door).

Increased the height of the wall directly next to point D.

Changelog:

Adjusted clipping in several spots along point D to be smoother.

Fixed a strange cubemap error from the last version.

Changelog:

Added a way to the high ground behind point D.

Adjusted the profile of the bunker next to the point E bridge to break up sightlines.

Adjusted red respawn times immediately after points A and C are captured to be less punishing for red players who were in their spawns when they were deactivated.

Fixed an untextured face underneath a bridge.

Fixed a trigger_hurt not fully encompassing the water at point D.
