Vulpecula a3

Just a tiny update before the playtest. Downscaling is likely still to happen.

-Fixed some overlays no longer being associated with brush faces that were turned into func_details.
-Two new small ammo packs.
-Adjusted targets for the main bridge jumppads.
-Fixed a singular blue prop on red's side of the map being the wrong colour.
-Clipped more spots that were meant to be inaccessible.
-Adjusted platform from the vent route to be less airblast-campy.
-New arrows to help guide the player.
-Turned some more geometry into func_details.
-Many other small unlisted layout changes and fixes.

Last update before I work on downscaling the map!

-More team recognition across the map.
-Fixed standing on certain team siren props on the walls.
-Increased the width of the building closest to spawn.
-Entirely reworked the bridge jumppad area.
-Gave the bridge jumppad a hologram outline to make it more obvious.
-Cut down on many instances of unused/unnecessary space.
-Reworked the sniper balcony at the top of the map near spawn.
-New vent route from the mid area to the enemy's intel with a one-way door.
-Changed the snow environment particle to be visible from further away. (Thanks Gokrow!)
-Many health and ammo pack changes.
-Way more func_detailing, cutting down on compile times and increasing performance.
-Better lighting around the map for team recognition.
-Many other small unlisted layout changes and fixes.
