Title: Fixed an off-by-one error in isOverAxis in Droppable and Sortable.

Fixed an off-by-one error in isOverAxis that was not taking the first pixel of the given axis into account. This caused droppable elements to not detect draggables placed on the first pixel of the droppable, which resulted in one-pixel spaces between droppable areas that should have been flush with each other.
