Move permission check code to hyperdb Now the hyperdb has a method filter_with_permissions that performs the permission checks before (for filtering on sort/group/filterspec arguments) and after a call to hyperdb.filter. This also fixes possible problems on the unfiltered sort/group/filterspec arguments in roundup/rest.py and roundup/cgi/templating.py
