jp roster name manegement + Pipe transfer
- added experimental pipe transfer protocol (based on xep-0096) - jp now manage roster name to jid conversion (if an argument correspond to a roster name, it replace it with the corresponding jid) - jp now add last known resource of when a resource is needed but we have a bare jid (e.g. for file or pipe transfer)
