	  object ref count cycles, now GladeProject just releases all widgets from the project
	  and keeps a reference to the GladeWidget instead of the GObject, GladeWidget is now
	  GInitiallyUnowned and GladeProject assumes ownership when objects are added to the
	  project (glade-gtk.c in this patch avoids needlessly adding a widget to the project
	  that will be implicitly added, now glade-gtk.c does not directly manually add any
	  widgets to the project).

	  The problem at length was an issue of orphaned project widgets left in the project model.

	ChangeLog

	  fired before modifying internal data structures (and dont use the glade_util_ function
	  to find a widget iter).

It is sometimes possible that children are added before their parents in the tree. We simply
ignore that for now as it doesn't cause any harm in the tree model.

	Implemented preview feature for Glade.

	* gladeui/Makefile.am, gladeui/glade-previewer.c: Added program to preview
	  glade files.

	* gladeui/glade-project.[ch]: Implemented glade_project_preview() to spawn a
	  child preview process, reap it when it dies and close all previews when
	  project closes.

	* src/glade-window.c: Added toolbar button to spawn the preview.

	* gladeui/glade-xml-utils.[ch]: Added glade_xml_dump_from_context().

	* plugins/gtk+/glade-gtk.c, plugins/gtk+/gtk+.xml.in: Added actions to preview a widget.

	* gladeui/glade-app.[ch]: Added glade_app_get_bin_dir() for resolving of previewer path.

	  just a hack to enable building glade for 2.0 while it doesnt run for 3.0.
