[FIX] xmo@openerp.com-20120209090214-84d6jjr1jnf32kpi excluded too many fields

previous change would exclude all fields with @readonly, but @state can remove @readonly from fields and means fields are importable again (pretty much). Need to add that, otherwise it's almost impossible to import stuff
