xml.user.login / Add user information in response

[fxp]

Instead of returning only the login status

<?xml version="1.0" encoding="UTF-8"?>
<ok/>

Add the user information (without password) to the response :

<?xml version="1.0" encoding="UTF-8"?>
<ok>
  <record>
    <id>2</id>
    <username>fx</username>
    <surname>Prunayre</surname>
    <name>François-Xavier</name>
    <profile>Administrator</profile>
    <address>313 Chemin du four</address>
    <city />
    <state />
    <zip />
    <country>fr</country>
    <email />
    <organisation />
    <kind>other</kind>
  </record>
</ok>

Add info=true parameter to maintain backwards compatibility (discussed on IRC 20110308)
