Hooking up xpinstall to the viewer. This will cause a new instance of the

xpinstall to be created when the viewer launches.  This will be removed
(along with the startup of silentdl) once we have a way of starting up
components less intrusive.

nsViewer.cpp - Added CreateInstance and related code to start component
makefile.win - Added new include path
