In pubsub, subscription items include and 'affiliation' attribute which is not in the schema

Patch removes the offending attribute.

Was the attribute "affiliation" removed in the spec? If yes then this patch is fine by me.

Version 1.12 Subscription schemas

Namespace: http://jabber.org/protocol/pubsub#event

<xs:attribute name='node' type='xs:string' use='optional'/>

Looks like this was a change between version 1.7 and 1.8 of the spec. Since the server is supposed to be 1.8 anyway, I will commit this patch.
