Changes for the photon platform - they should not affect build/runtime on other platforms.

nsWidget.cpp
	- fixed the problem with context menus not showing up in the Mail&News client.
nsWindow.cpp
	- fixed a problem with the PtRegion underneath the menus not being realized in some cases
	( not related to the change in nsWidget.cpp ).
