xmlrpc: more correct re XMLRPC spec re. no type specified, defaults to string

- This will allow you to receive docs like <value>mystringvalue</value>
- instead of only allowing <value><string>mystringvalue</string></value>
- according to spec if no type specified, assume string
- allows kamailio to receive messages from apache ws-xmlrpc which doesnt specify string type
