Alpha 4 - lots of visual changes!

- Added a bunch of stuff to the 3D skybox (not finished yet!)
- Replaced ramps with staircases
- Prettied up the area around point A
--- This is likely a finalized look for the area around A.
- Replaced most (but not quite all) dev textures with proper game textures
--- This is not a full part pass yet for areas beyond the center of the map, but was done to give the map a slightly more "finished" look. I'm not planning to make any further major layout changes, so I feel comfortable doing some detailing.
- Fixed a case where players could stand on top of a fence near RED's forward spawn near point A
- Adjusted the ramps next to point C on both sides
--- Slightly moved health and ammo beneath the ramps to accommodate for this
- Moved crates used as cover in the warehouses between A and B to be under the bridges to B instead of awkwardly sticking out from beneath them

Alpha 3A hotfix!

- Fixed Engineers being able to build in a spot they shouldn't in the hallway outside the spawnroom at point C
- Added health and ammo to the lower attacker entrance to C

New upload under a new name!

- Changed the map name from Ditch to Alleyway
- Widened the area around point B for less crowded combat
- Widened the area between points B and C
- Widened the room containing point C
- Reshaped the high wall above the attacker entrance to point C
- Added a new route from the building between A and B leading directly to the balcony above B
--- Added additional cover and moved health and ammo packs to accommodate this
- Widened the pillars in the building between B and C to shorten a long Sniper sightline
- Replaced dev textures on floors to start experimenting with theming
- Replaced many dev textures at mid to start experimenting with theming (I'm planning to use an urban theme like those seen in maps like Kong King and Mannhattan)
- Added health and ammo packs to the lower attacker entrance to C
