Encapsulated name tracking mechanism

	* gladeui/Makefile.am, gladeui/glade-name-context.[ch]: Encapsulated name tracking mechanism

	* gladeui/glade-project.c, gladeui/glade-command.c: Now added a naming policy to the project
	with prefs and load/save support + a glade command to set it - also revamped the prefs dialog,
	it also pops up automatically for new projects.

	* gladeui/glade-editor.c, gladeui/glade-editor-property.c, gladeui/glade-property-class.c,
	gladeui/glade-property.c, gladeui/glade-widget.c: All effected since now 
	glade_property_class_make_gvalue_from_string () needs a GladeWidget argument to do
	hierachic context sensitive searches... that and naming is much cleaner now.
	
	* src/glade-window.c: remember to pass ownership of the project to the app.

	* plugins/gtk+/glade-gtk.c, plugins/gtk+/glade-column-types.c, plugins/gtk+/glade-model-data.c:
	BEWARE: Dangerous and still a work in progress.
