Tidepool a3

Reworked the first stage entirely, so it now somewhat resembles an aquarium if you look past the dev textures:
-Moved Capture Point 1 into the Aquarium
-Added a seal exhibit
-Added a toad exhibit
-Added catwalks above the aquarium floor
-Added a new flank on the ground floor around Capture Point 1
-Removed various sniper sightlines in the Aquarium
-Wondered what the hell I was thinking with the mess of doors that was Spawn 2 and replaced it with a more streamlined spawn
-Added barriers to Spawn 3 so it's obvious which way you're meant to exit
-Various door fixes
-Added giant pipes to the tidepool
-Added an additional flank route out of the tidepool
-Most importantly, I made the payload a shark.

Added an env_tonemap_controller to satisfy Mecha Engineer

Fixed a bunch of missing models since I didn't know how to properly pack the map.
