Log Message:
Changes 1.1.5:
* It was not possible to delete multiple connection attributes using the \ 
OPT_CONNECT_ATTR_DELETE option. This can now be done using the std::list< \ 
sql::SQLString > type.
* MySQL_Prepared_Statement::getMoreResults() functionality has been implemented, \ 
so multiple result sets now can be fetched using a prepared statement.
* The following connection options have been implemented: MYSQL_DEFAULT_AUTH, \ 
MYSQL_OPT_CONNECT_ATTR_DELETE, MYSQL_OPT_CONNECT_ATTR_RESET, \ 
MYSQL_OPT_LOCAL_INFILE, MYSQL_PLUGIN_DIR, MYSQL_READ_DEFAULT_FILE, \ 
MYSQL_READ_DEFAULT_GROUP, MYSQL_SET_CHARSET_DIR, and max_statement_timeout for \ 
session-based query timeout.
* These functions were added: Connection::isValid() checks whether the \ 
connection is alive, and Connection::reconnect() reconnects if the connection \ 
has gone down.
* The Boost dependency was removed from the Connector/C++ API headers. These \ 
headers were using the boost::variant type, making it impossible to use \ 
Connector/C++ binaries without having Boost installed.
