Before this change, sqlite3::connection::execute silently ignores statements after the first one (separated by semicolon). After this change, trailing statements are detected and an sqlpp::exception is thrown. This change also adds documentation to other connectors indicating that execute is supposed to be used with single statements only, even though it is possible to do otherwise.
