- Avoid changing project selection when selection is cleared, selection get's cleared
	    when the user changes a widget name and a filter is applied (removing the entry from
	    the filtered model), avoiding syncing project selection avoids making the editor disappear
	    when the user changes a widget name (fixes bug 604322).
	  - Also plugged some leaked objects retrieved by gtk_tree_model_get().

	* gladeui/glade-editor-table.c: Fire a warning when entry is edited with no widget
	  loaded, also change the ->loading flag strategy for blocking signal emission instead.
