GUI interface still not quite working. Two issues:

* PyQt4.QtSql's SQLite interface doesn't appear to return the same results as the SQLite browser. This is probably me depending on a bad data ordering assumption.
* QSqlQueryModel isn't set up to have the db change from underneath it, AFAIK -- have to add the ability to notify it there's new data.
