* add a 'REQUEST=None' parameter to every render_view method:
   * new patches in FormulatorPatch to fix render_view of Field, Widget,
     MultiItemsWidget, LabelWidget, FileWidget, PasswordWidget and RadioWidget
   * reorder parameters in OOoChartWidget.render_view
   * add a 'REQUEST=None' parameter to DurationField.render_sub_field_view
 * forward REQUEST to field.get_value in:
   * ListWidget_render_view (my goal)
   * TALESWidget_render_view (why not?)
 * PatchedLinkWidget.render_view and
   MultiRelationStringFieldWidget.render_view
   needn't call get_request anymore if REQUEST isn't None
 * PatchedLinkWidget.render_view: change REQUEST.get('cell') into
   getattr(REQUEST,'cell',None) since 'cell' may be an attribute of REQUEST
 * add a unit test to check the signature of all registered fields/widgets
