[patch]ConfusedMovement

[lukaasm]

Update confusedmovement generator to take into consideration LoS collisions so we won't fall under map and go trough walls anymore ;]

w/o checking detectposcollision in config so if getnearpoint can't find point in los we always get point where collision occurs

Should compile fine, but can't check it now ;f

The same needs to be done for FleeingMovementGenerator

getNearPoint will not return LOS-fail point.

[lukaasm]

but should find point in los if possible ;p but sure we can erase that if check for config detect detectposcollision ;p

[VladimirMangos]

confused movement is random, we not need exactly selected points (or near search), we can just skip any problematic.

Current LoS functions don't consider terrain, and that's the biggest problem of confused movement, moving player below terrain level.
