Trivial fix in DnD drop + slideback

[Willem Rein Oudshoorn]

The following patch implement the slideback functionality.
Also a operator precedence bug is fixed (SR # 100253).

Slideback numbers are now hardcoded.  Also Apples docs.
say that slideback is disabled when icon animation is disabled.
This is not implemented, it will always do a slideback when asked.

        * Source/SharedX/XGDragView.m: changed and added comments in a few
        places.
        (SLIDE_TIME_STEP, SLIDE_NR_OF_STEPS): #define numbers controlling
        slide (back).
        ([XGDragView
        -dragImage:at:offset:event:pasteboard:source:slideBack:]): use
        slideBack: argument
        ([XGDragView -_handleDrag:]): renamed a local var, and use
        slideback.
        ([XGDragView -_handleDrag:]): fixed bug in determining if we do a
        DnD drop SR#100253. (operator precedence was wrong).
        ([XGDragView -_updateAndMoveImageToCorrectPosition]): use new
        method to display drag image.
        ([XGDragView -_moveDraggedImageToNewPosition]): new method that
        will do the drawing and moving of the DnD image.
        ([XGDragView 
-_slideDraggedImageTo:numberOfSteps:stepswaitAfterSlide:waitFlag]):
        new method that implements sliding the DnD image.
        ([XGDragView -slideDraggedImageTo:point]): is implemented with the
        use of the method above

        * Source/SharedX/XGDragView.h: added instance variable, slideBack.
        changed comments, added prototypes for new methods.  (See XGDragView.m)
