Close/abort query on client (http) disconnect

[booo]

At the moment there is no notification about client disconnects. We need an event to abort/close the database queries. Check if node-postgres provides a function to close/abort a query.

On disconnect => abort query.

This should be used in the request handler. But first of all we need tests ;)

res.socket.on('close', function() {
    queries.close()
});
