Tibet a22

- Textured the ground because why not
- Moved blue forward spawn for attacking point 3 up to the level above to break sightline from red defensive position.
- Added a medium healthpack to aid blue's push.
- Slightly reduced blue's respawn time for CP3 and increased Red's.
- Some arrows and stuff.

- Tweaked pickup locations
- Added red forward spawn for defending CP3 as the new final put them a bit further back
- Added an arrow that raises to direct blue to the new spawn exit after CP1\
- Clipped top floor of rocket platforms

Fixed no respawn room visualizer on top of red final spawn.

Adapted Ravage's WIP finale.
