XWIKI-8946: Remove support for initial import by guest of an empty wiki in the security authorization module
XWIKI-6903: Office preview fails for PDF attachments
* Improve the checks done by the office viewer to detect if a media type is supported (i.e. if it can be converted to HTML). The consequence is that PDF attachments won't have the eye icon any more.
* Improve the check for presentation format in office importer, office viewer and WYSIWYG editor server.
* Refactor a bit the office importer because I need access to the document formats registry to be able to detect correctly if a conversion is possible. Note that DocumentFormatRegistry interface is from JODConverter but it is generic. Wrapping DocumentFormatRegistry, DocumentFormat and DocumentFamily with our own interfaces is not worth at this point IMO.
* Remove more mentions of "OpenOffice" from the office modules.

XWIKI-8934: Delegate to the model the parsing of rights objects

 - This reverts partially commit 5ae6cc23c8315f281c71d03d63bb302d7916e0fc since classes used by RightsClass are not properly derived from ListClass
 - Improve level parsing by using the custom class
XWIKI-8934: Delegate to the model the parsing of rights objects
