view JID/resource instead of JID in the sender box in single messages
Currently, when single messages are received, in the "sender" field only JID is displaied. I would like to see JID/resource. Knowing the resource is generally useful. It may show from where or with what client the sender wrote its message.
An other reason for that is that some bots may add meaningful resources to messages. For example, the PyListC component broadcasts messages to several users. Messages come from the component so the sender JID is the component JID but the real sender JID is added in the resource (with @ -> % like in gateways). Other bots may add resources with other meanings.
