Moving the wet tech of ut4_raid forward.

.map is included, so you too can make nifty rain and swirling water. Check out the stability fix
for the ships - players don't get stuck so much when there's a second hull.

2-3 nights total to construct. Complex action in the rain and water shaders. I think it worked well. :)

r2: Fixed a spawning problem, added more ship stability, added lightning, shadered out the ship, and various tweaks.
