pulling sourceforge changes and dll/so copy issue

1) auto copy mysql dll (so) to binary folder (mysql tests could be runned without adding dll (so) to <PATH>;
2) commenting two test on mysql that have problems on MySQL 5.5.25a
3) change type=InnoDB to ENGINE=InnoDB;
4) adding SOCI_MYSQL_TEST_CONNSTR to auto insert CMake parameter into test;
