Make sure Web Message events are properly reindexed after creation, before the fetch_incoming_web_message_list alarm is run

thinko: inverted logic

Don't fail if a previous --save test was interrupted before cleanup.

Delete in beforeTearDown() the person that was added on afterSetUp().

In ERP5, objects that do not acquire local roles (according to their portal type configuration) do not need to be reindexed with their containers.
So do not reindex recursively if portal_types of contained objects don't need it.

Security reindexing can be customized with a type-based method.

Fix test that wrongly relied on unrestricted access for updating object roles.

Don't fix the default_encoding at import time as it can be overriden later (ex. by a later import of zope configuration).

Don't assume objects to be str if they're not unicode

If they coincide with imported keys.

a bit modify previous commit ba435293, use untouched message for default, and explicitly convert to unicode for non existing case.

support non-ascii msgid and add a backward compatibility for the existing catalog that stores non-ascii msgid as str not unicode.

  * to_str does not return str result
  * typo in variable name

call activate() in the same transaction otherwise we may get lots of UnsupportedWorkflowMethod errors.

Also, use local imports of itools where this is still necessary,  and remove all mention of itools from ERP5 code.

Instead of itools.gettext

Remove files/functionalities not needed by ERP5

Fork from master branch of Localizer and 0.50 branch of itools into ERP5

Remove almost everything from itools except bare essentials needed by a stripped Localizer for ERP5

Follow up the commit 4b16e1dd (use UnrestrictedMethod's super user instead of ad-hoc SUPER_USER.)

so client (browser) can draw an image out of it
