Use more generic node instead of File/Folder

The phpdoc for the sharing functions was very restrictive. As a
consequence passing node object (for example from the OCS Share API
where we don't really care if it is a file or folder), would actually
be invalid.

With this loser restriction the interfaces become more generic.
