EARL patch up SPARQL

From: Jeremy Carroll <jjc@hpl.hp.com>

Message-ID: <461E428E.4080205@hpl.hp.com>
To: GRDDL Working Group <public-grddl-wg@w3.org>

I had an action to write some SPARQL, it's attached, and so is the fixed 
up version of the EARL that Chime sent recently.

It applies the following heuristic:

If two tests have the same input document, and one passes and the other 
fails, then the failing test was not applicable.

It deletes such
   ?s earl:validity earl:fail triples,
and replaces them with
   ?s earl:validity earl:notApplicable ones

It also adds the t:inputDocument triples used to make such analysis.

This is a little unsatisfactory because I am changing someone else 
earl:Assertion's, rather than making new ones.

I have an alternative query that actually makes new assertions, also 
attached, but it doesn't work :(

Jeremy
