turn all the stuff used to handle 'generic relations' in forms into proper field / widget. -> regroup code from web.request, web.controller, web.views.autoform, web.views.formrenderers, web.views.editcontroller (!) into GenericRelationsField, GenericRelationsWidget in the editviews module (together with the UnrelatedDiv view). So: * almost everything in one place * no more specific behaviour in the form renderer * almost no custom behaviour in autoform (simply add the field when it think it should) Also, the form renderer now display field's value with colspan=2 when field.label is None.
