func_detail_fence brushes affects visibility culling (when they shouldn't)

[victorbstan]

Using a texture with alpha mask and setting it to func_detal_fence causes meshes on the other side to be culled. Where I would expect them to not be culled, since the fence brush is usually used with alpha masked or transparent textures. A temporary fix is to change func_detail_fence to func_wall, this prevents the culling of meshes other side of the fence texture. I have included some screenshots and a test .map and compiled .bsp file and the used .wad files in this map.
