Enhanced MoveTo, fixes #1074568

  MoveTo <int|*> <int|*> <Reference Corner>
   - * means "use current value"
   - Reference Corner is one of:
     - UpperLeft, Upper, UpperRight
     - Left, Right
     - LowerLeft, Lower, Right
   examples:
     MoveTo 0 * Left       -> snap to left workspace edge
     MoveTo * 0 Lower      -> snap to lower workspace edge
     MoveTo 0 0 UpperRight -> snap to upper right workspace corner
TODO: perhaps add some "aliases" to make it more userfriendly
