Getting/Setting text attributes for a GtkEntry

[Oisin Boydell <Oisin Boydell Sun COM>]

The GtkEntry object does not support text attributes so the 
atk_text_ref_run_attributes() function will return NULL (which indicates no 
attributes set) when called on a GtkEntry.
A GtkEntry is editable but since it does not support text attributes a call to 
atk_editable_text_set_run_attributes() will return failure.
