SpecialWikibaseQueryPage::formatRow is no longer abstract

Moved the most common implementation of it into the base class since it seems like the natural
formatting in the usual cases which can easily be predicted since we are always dealing with
Entities (or rather entity IDs) as results to be displayed.

Also cleaned up several redundant doxygen comments, simply use @see rather than having copies
of whole member signatures when overwriting them in subclasses.
