Radiophobia 3 - NPCs can't see through bushes file

Makes all bushes completely opaque to NPCs and bulletproof so that it can't be abused by the player. Not the best solution (which is why it's optional) but it is the only one available due to how the engine works.

Install by unpacking into the game folder and overwriting the contents.

Note: Remove "gamemtl.xr" and rename "gamemtl.xroriginal" to "gamemtl.xr" in case you want to revert.
