fixed QueryExecuter to deal with multiple errors

previously it was throwing a SQLException as soon as the error message was
received from the backend. This did not allow the protocol to finish properly
now, simply collects error messages from the backend until the query is done
and throws exception at the end
Also added setLogLevel to Driver.java, and made the log levels public
