Attempt to fix problems with multimon windows. The mouse position 

reported by the synergy hook dll is in a space with 0,0 in the
upper-left which is not necessarily the same as the virtual desktop
space.  So the windows primary screen now accounts for that.  On
the secondary screen, mouse_event() doesn't seem to accept negative
coordinates even on the windows NT family, making monitors with
negative coordinates inaccessible via absolute moves.  So if the
move will be to negative coordinates, use the windows 95 family
fallback of absolute moving to 0,0 then relative moving to the
final position.
