initial refactoring for interfacing the game engine from the ios frontend (game doesn't run yet)

I'm not saying this fixes anything, I'm just hoping it inspires Tiy to take an interest in the theme. (removes the background water effect that just wasn't working, puts in new spray objects including removing the copyrighted one, tries for a sand that doesn't look like sandpaper)

merge in japanese updates

An experiment - make bazooka AI use float instead of hwFloat - should be as accurate, but faster.

Allow head of rope to attach to hogs/barrels/crates again. Rope still does not, to avoid the bug.

Try to allow cursor to reach water when zooming out

Make AI switch to amNothing before trying to walk if it holds weapon which needs targeting (not tested)

Add 'Cancel connection' button. Fixes issue #162

Send server's name in udp packet. Fixes issue #25

adjust crosshair criteria again. this should take care of sniper rifle and crosshair after attacking

update dejavu - might possibly fix the german/brazillian/swedish crasher, who knows.

Start implementation of archivements/ratings on server side: replay saving routine

Show winners in console in a special form so this information could be easily parsed

cleared up Random Weapons and implemented remembering of weapons in Balanced Random Weapons too, also seems to work
