N°2847 - Refactor some early choices

- TWIG: Change calls to object methods from simple notation (eg. oObject.Id) to complete notation (eg. oObject.GetId()) to avoid confusion with use of arrays and variables (eg. aObject.sId)
- UIBlock: $sId should not be first parameter as most of the time it can be ignored and generated by the system
- NewsroomMenu: Rename method for something more less ambiguous
- Html: Embed content in <div /> so we can easily find all such HTML fragments in the UI
