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)
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.
Make AI switch to amNothing before trying to walk if it holds weapon which needs targeting (not tested)
Add 'Cancel connection' button. Fixes
