ecere/gui/drivers/XInterface: Fixed debugged application staying on top of IDE (regression)
- Broke this trying to fix Metacity complaining about using CurrentTime here, but when
  ActivateRootWindow() is called we really need to take over, otherwise a debugged application
  stays on top of the IDE when we hit a breakpoint (there was no user interaction with the IDE,
  but it really should be activated)
