Cache.Storage.MySQL is incompatible with current mysql driver

Cache.Storage.MySQL is not working well with current Sql.Sql module because of binding variable syntax change.
ex.
where cachekey='%s'
causes SQL syntax error, throws sql query:
where cachekey=''foobar''
Binding variables quoted with double single quote.
I've patched that module, and now it's working as far as I've tested.
