* src/glade-app.[ch], src/glade-project-window.c:
	  Added glade_app_update_instance_count to keep track of
	  (and differentiate between) multiple projects with the same name.

	* src/glade-project.[ch]: Added instance count member to project
	  object, also ensured that project->path is always a full path.

	* src/main.c: fix leak of list of initial projects to load.
