SàT: multi-profile, plugins updated

- core: 2 new convenient methods: getJidNStream and getClient
- new param in plugin info: "handler" to know if there is a handler to plug on profiles clients
- plugins with handler now use an other class which is returned to profile client with the new method "getHandler" and pluged when connecting
