more aggregate tests

I've committed several aggregate tests to CVS for AVG, MIN, MAX, SUM and SAMPLE [1]. I've guessed in a few places what the correct results should be (especially for SUM and AVG) based on my understanding of the current spec text, the numeric type promotion rules and whether a system produces canonical lexical forms. My system passes all of the new tests.

I've also updated the default prefix URI in the aggregate, project expression, and property path manifest files so that all tests consistently use namespaces within the /2009/sparql URI space.
