Legacy A4 upload

Map test go better when you upload the map.

Messing around and changing some things.

Changelog:

- Changed the room behind the point completely, it should be a bit more fun to fight in now
- Extended a bit of cover at the front of the point
- Added some details to show playerclip barriers
- Added some displacement alphas and textures for some extra detail
- Brightened skybox lighting and increased its angle

ANOTHER remake. This time Legacy is actually looking decent. I took the feedback of the water by the point being the only interesting thing about A2 and made Legacy a sea-side beach brawl.

A1 had a number of problems with it's design that would basically force me to cut out vast swaths of map to make it any good, so I figured why not just start form the beginning with a new map.

Remade the entire map.
