Evaluate on all topics instead of those with documents retrieved (#108)

* Added TREC7 and TREC8 qrels (primarily to avoid confusion with the WT qrels in `qrels/qrels.401-450.txt`

* Missing TREC7 topics files

* Change default to setting also used in the "official" evaluation

* Add -c flag for trec_eval

* Revert "Change default to setting also used in the "official" evaluation"

This reverts commit 85b13df.
