erp5_web: reuse the web section logic

bt5/erp5_web/SkinTemplateItem/portal_skins/erp5_web/StaticWebSection_getDocumentValue.py

-"""
- This script is part of ERP5 Web
-
- ERP5 Web is a business template of ERP5 which provides a way
- to create web sites which can display selected
- ERP5 contents through multiple custom web layouts.
-
- The default implementation searches for
- documents which are in the user language if any
- and which reference is equal to the name parameter.
-
- Other implementations are possible: ex. display the last
- version in the closest language rather than
- the latest version in the user language.
-
- NOTE:
- - the portal parameter was introduced to
-   fix acquisition issues within the _aq_dynamic
-   lookup from WebSection class.
