Pcbnew: Check if user wants to warp mouse to origin of moved object

CHANGED: When moving a footprint, Pcbnew was always warping the mouse
to the origin of the moved object regardless of the state of the "Warp
mouse to origin of moved object" checkbox.  This MR now honors the
state of the checkbox when moving footprints.
