pl_icechiller a3

- Reworked last point
- Moved Blu's last forward spawn
- Moved 2nd point further back, with the new 1st point playing better than a1's, ill be adjusting where the rest of the points stand, need some more tests to see how well red defends each point
- Some small lighting adjustments

- Rework of the first point and third point
- Changed some spawn timers and added 2 more forward spawns for Blu
- Changed to night theme (might as well get some practice on how to do lighting)
