glade_default_app_selection_clear() Add call to glade_util_clear_selection

	* src/glade-app.c: glade_default_app_selection_clear() Add call
	  to glade_util_clear_selection () so that placeholders selection
	  also gets cleared.

	* src/glade-editor.c: Make ((GladeEditorProperty *)prop)->signal_prop a
	  weak pointer to the said property, this way we avoid crashed when
	  leaving dangleing pointers from canceled query dialogs.

	* src/glade-project-view.c: Added GTK_IS_WIDGET() clause avoiding
	  dumb warnings.

	* src/glade-property-class.c: Fixed "name" on custom properties to
	  be retrieved from there pspecs, also gave "default" and "name"
	  tags precedence to those found on the pspec.

	* src/glade-widget-class.c: Fixed a hidden segfault waiting to happen.
	  fixed order of derived custom properties (used g_list_append, not
	  prepend for this special case where the order matters and we cant
	  just g_list_reverse).

	* src/glade-widget.c: Added GTK_IS_WIDGET() clause avoiding
	  dumb warnings.

	* widgets/gtk+.xml: Removed unused glade-parameter stuff.
