This reverts commit c9aac11f.

On draft, we should allow to register password on the credential.
So credential update can be used to change user password without proxy.

Set auditor proxy role to Base_getConversionFormatItemList. Anybody should be able to view conversion format list.

When render dashbord, we should look if we use anonymous gadget
When get active knowledge pad, do the same for anonymous and for user else we can get the wrong active gadget (ex : when rendering login_form on web site root, we get front pad for anonymous and default_section_pad for connected)

Transform all standard field to proxy field in the credential library

Use Embebed File not Image
Add property sheet to Credential Update
Update portal types

Enhance consistency with response creation dialog on events

- test_suite_title
- test_node_title
- project_title
This allows to remove some hack on master to retrieve the project,
and to have more control on parallel instances

remove obsoleted worklist started_event_lis

getTextContent is now more consistent with the other accessor (getContentType, getTitle, ...).

In case of multipart/alternative, try to get the content type defined on preference.
Return first text part in case of multipart/mixed.

- Update action Messages
- improve marshalling of URL parameters
- fix typo

if erp5_crm is installed, service list for events is returned otherwise all validated ones.
