* gladeui/glade-project.c: Added "parse-began" signal

	* gladeui/glade-design-view.c: Hide workspace and show load progress
	  while loading so that one cannot access project widgets during the load
	  (insensitive workspace was problematic and causing some loaded project
	  windows to be permanently insensitive).

	* src/glade-window.c: Avoid any messups during project load, cannot close
	  projects while they are loading, etc.
