a few useless methods

in order to remove hardcoded 'transition_' or 'script_'

non-existing getWorklistValueDict one
+ add getGuardRoleList method on DCWorkflow worklists

in the Workflow, the status dict (used to set history) can handle None
values, and the behaviour should not differ from DCWorkflow.

This should fix SyncML test failures.

remove duplicated code

call scripts by their old name

ERP5Workflow: add acquire_permission_list attribute, setup acquisition of permission/roles correctly when converting, rename methods

WIP
todo: remove property in property sheet
persistent mapping will take care of changes on the dict and commit them in the ZODB
otherwise, because we change the attributes of the dict and not of the State object,
the changes will be lost

state_permission_roles attributes should be updated when the permission list is changed on the workflow
it also fix matrixbox edition (was crashing when permissions where added)

+ remove unused dependencies

instead of getXXXScriptIdList, which calls getXXXScriptValueList anyway (-> bad performances)

and modify checkGuard to have expected behaviour

this fixes error when accessing to special views on Transition objects
it also remove duplication of guard properties (they were stored in the
properties of the guarded object *and* in a guard object)

Adding List to the end of the getter of a given property will return
an instance of type list.

because Variables are only about Workflow

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

+ rename update_always to automatic_update as is should be
