* src/glade-editor.[ch], src/glade-editor-property.[ch], src/Makefile.am:
	  Revamping of the glade-editor, wrenched out the GladeEditorProperty code
	  from glade-editor.[ch] and created glade-editor-property.[ch], lots of
	  code cleanup all around and now GladeEditorProperty is a GtkWidget with
	  a smooth encapsulation, transperent derivitives for different pspec types
	  and can now be used standalone inside custom editors.

	* src/glade-property.[ch]: clarified recursion protection with "syncing" var.

	* src/glade-property-class.c: Now consults glade_editor_property_supported instead
	  of the old glade_editor_editable_property.
