bball Ozone rc4

Noticed a few issues during a playtest, hopefully I can finally leave this map as is.

• Shortened the reeds to visually match the heigh of the blockbullets brush
• Removed the ability to splash off the rooves of the houses
• Added corn (yum)

• Updated the fences so you can now walk around the edges
• Fixed the compile so cubemaps should now work
• Actually final compiled now
• Removed bullet collision on the backboards

Accidentally compiled without clipping visgroup ticked

-Removed the broken bridge
-Textured the outside of the map for spectators
-Adjusted some of the detailing
-Aligned the backboards to be symetrical
