add SOAP options to base client

[messageagency]

It would be really useful for me to be able to send options to the SoapClient() call in SforceBaseClient::createConnection, especially for wsdl_cache

http://php.net/manual/en/soapclient.soapclient.php

I'm adding a minor commit that implements this feature.
