lclplant a6

• The stage now connects to stage 2/chemplant correctly and without seams (but chem is still visgrouped out)
• Simplified B and added a high ground route for attackers and defenders to consider. It might be too powerful.
• Simplification entails: fewer entrances/exits to B's ring, better lighting from sky light (it's open air now), fewer weird dev materials in odd places, and cleaned up brushwork.
• A completely new connector is now present in the tunnels between A and B. The map should be more balanced as a result, but it's not very architecturally interesting and it may need spawn times to be adjusted to match it.

I've also added a new route to A's upper ground to attackers on the far left. It may not play well; I was just experimenting.

• Finally remade Blue's spawn exit; red no longer has a sightline through the whole spawn from the side room. The side door is now much larger and splits off through a hallway. Hopefully this will make spam in general a little bit easier to manage.
• A's ceiling route has some experimental sight-blocking pipes on the attacking side to make RED engies stop using it.
  
• Gave Blue a route up to B's height, but added cover for red nearby.
• Opened up B to sunlight

Additionally, pickups got redistributed a little bit, and the height of some rooms near Blue spawn was adjusted.

• Added/brightened lights everywhere and added windows to exterior walls
• Added a place for blue to congregate close to B and a new route to it
• Changed Blue spawn's side door to a regular setup door
• Clipped off things all around and tightened up geometry
• Metal is more prominent at B

I didn't change the upper route at A besides brightening it; still haven't seen any instance of it being abused.

• Built a bridge across the road on A for blue to cross
• Scaled the outer ring around B out a bit
• Added some cover at B for red to build behind
• Shrank B's cap zone by about 25%
• Added some cover between A and B
• Made connectors from a little A->B longer

In response to the testing:

1. Red spawn is closer to B
2. Blue spawn is closer to A
3. A and B are slightly further apart.
4. Misc improvements like clipping, sightlines, round/cap times.

• Rotated last relative to the rest of the map
• Closed off two of the doors to last from the outer ring
• Revised connections between spawn, last, and A
• Added some lighting and signage
• Reduced spawn wave times for both teams.
