having empty my_for_status.xml file was leading to ExportError

- move group to propertysheet Guard/guard_group
- move permission to propertysheet Guard/guard_permission
- move expression to propertysheet Guard/guard_expression
- move role to propertysheet Guard/guard_role
- remove description (portal type Variable should use Property sheet DublinCore instead)
- move automatic_update to propertysheet WorkflowVariable/automatic_update
- remove for_catalog
- move for_status to propertysheet WorkflowVariable/status_included

use DublinCore property sheet

- add anchor on worklist listbox
- change state_type_list to list instead of string in state view
- add listbox for trigger_type for nice display of trigger type in transition view

portal type

because Variables are only about Workflow

imtroduced in previous commit

get workflow-related property sheets back to erp5_property_sheets bt5
rename actbox_* properties to action_box_*

for possible transition selection on a state and rename my_destination_title_list
to my_destination_list

how transition is triggered instead of '1' and '2'

Portal Type because of initialization problems when associated to Workflow Tool

+ rename update_always to automatic_update as is should be

as only WorkflowTool is concerned and new property sheet can be completed
with properties other than constraints if needed.

work in progress

and rename a few others 'Default *' to 'Variable *'
and change Variable_getNonEvaluatedInitialValue to Variable_getNonEvaluatedVariableValue

regression in a2ce533c5d2 due to missing parenthesis in 'or' statement

default_value was a bad name due to existing get/setDefaultValue on Base class

and dynamic_varible to dynamic_variable
