Disable back-face culling when rendering the Sides of the map, preventing a graphical artifact at the edge of water maps.

Browse Source 
By rendering sides even when they are back-facing, the water shader is
on top of a mesh instead of emptiness and this solves an old
"edge-of-map" graphical issue.

Taken out from D359 with vlad's agreement. See screenshots there for
more information on the exact issue.
