Changes on ERP5Security: Define getFacebookUserEntry to reduce code duplication
   Add facebook support for login and logout (optional) on erp5_core, xhtml and credentials.

Since the change for use of User ID this code should return reference and portal type of the ERP5 Login object.

  The implementation of external_login expects the reference of an Login object and the portal type of itself

Include draft of facebook Oauth code.

  This method and call is duplicated on several places

  The user can be present from diferent logins, password tool only works with ERP5LoginUserMager
  users.

Returning true allows to add movements to existing one, and this group shall
always separate them.

uid is used internally during recursive calls and using uid can lead to
traverse all lines of catalog.

Note: Generic code shall have no constraints at all.

It will protect against storing truncated data.

If 2 lines have the same effective date (catalog has a 1 second precision),
always return the validate and open first.

From Lukasz Nowak:

1- Compensation is undesired. (51c8a250)

  Raise loudly with message.

2- Disallow any compensation. (3c74ed07)

3- Emit more informative log. (534b2e77)

Also minimise activity hurricane by calling expand directly.

Open Orders are searched using indexation timestamp, which allows to see them
in "windows", and does not repeat expand if not needed.

Generate activities and allow to pass the tag. Use search and activate
everywhere which will allow to walk through objects without killing the cluster
even in case of really big documents.

Avoid calling isDivergent which can take few minutes to finish.

causality_state comes from well designed causality workflow, which informs
enough about delivery state. Fetching causality_state property is extremely
fast.

Notes:

Do nothing on 'calculate' instead of disabling *_causality_interaction_workflow as
these interaction workflows do not generate activities directly, and do work
that can't be postponed.

By contrast, 'calculate' transition of delivery_causality_workflow is modified
so that no 'updateCausalityState' activity is created by default.

This commit also update list of method_id which should not call calculate_causality
