Fixes various issues with selecting: sectors and duplicating them many times in a row, sprites and then deleting some of them (also adds set union ['] and difference [;] to RSHIFT); adds the ability to move all selected sprites in the XY plane in 3d mode with SHIFT-LMB and align to the grid in an absolute fashion with CTRL.
