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 a2ce533c 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

There was bad displaying and escaping on the list.

DynamicClassGeneration_resetDynamicDocuments interaction should be apply to _setTypeWorkflow... methods: resetDynamicDocumentsOnceAtTransactionBoundary method will be run when a transaction finishes (eg. self.commit() has been called).
