Vents and Chokes A5

This update does a few big changes to try and fix the choke before A to be less bad, and also: snow!

• Replaced some ground textures with snow to solidify an original aesthetic & bounce more light around the map (forgot who suggested this but thanks!).
• Added some snow cover props from KrazyZark's pack.
• Widened choke before A point.
• Changed A left side route & added new flank route to avoid potential OP sentry spot.
• Minor changes around the map.

I feel like A is reaching a decent state, but the other two points are gonna need a similar treatment. But hey, we're getting there I guess.

This update updates the map according to feedback received during the latest playtest

• Made A choke wider
• Removed stairs at A flank
• Removed a wall that obscured some pickups
• Made A flank floor see-through
• Fixed forward spawn visualizers and RED spawn teleporter
• Changed layout of doors that close after B is capped

Forgot to pack textures ma bad

The name is not final, just a funny. Don't feel like listing the changes right now remind me to do it later

Needed to fix a couple more things

• Reverted speed boost at rollforward section cos it made the cart go backwards too fast
• Increased width of platforms near BLU spawn for better navigation

Had to fix a couple things.

• Fixed RED spawns so now more than just 1 of them are functional.
• Added funny rollforward section after A & small rollback at C.
• Adjusted final payload explosion to do more damage and have a larger radius.

Just wanted to clean this up a little bit to make it hopefully playable.

General:

• Widened every chokepoint to make them less painful to get through.
• Decreased damage and afterburn of trigger_ignites to make lava less punishing.
• Removed clutter and redesigned some rooms to increase mid-range fights and decrease crampedness.

A:

• Widened flank route rooms and added booster near the point to cross to the other side (or jump from the cart track to the top)
• Fixed booster that launched you onto a ceiling from some angles.

B:

• Removed RED one-way and added one for BLU.
• Simplified B cap outside area.
• Redesigned outer flank to give it a better and more defined structure.
• Added small connector from outer flank area directly to the point.
• Added pipes.

C:

• Added deathpit at the far side of the cart route.
• Added new flank to nerf some sentry spots.
• Redesigned route from RED spawn to the B flank.
• Added booster to get from RED side to the B flank.
• Adjusted B flank booster so players no longer take fall damage from it.

Testing this with bots is a pain in the fucking ass because they either get stuck at a booster or near B (either at the one-way door or at a random ass wall they think they can walk through), so I don't think it comes even close to representing how the map actually plays. I hope these changes are good.
