View source for Telnet rc rewrite

==Abstract==
Rewriting the remote control and telnet interfaces has been a long standing issue. Once the new playlist is finished in 0.8.6, we can begin merging those two interfaces ... well in fact rewriting most of the stuff.

==Ideas/goals/...==
* use new playlist
* advanced shell/telnet features (autocompletion, history, ...)
* allow multiple remote connections on the interface
* authentification: should we have only one level or several ?
* make it possible to "browse" the modules like a file system. This would be usefull to change variables which registered callbacks on the fly. (On a developer's point of view it would also simplify visualisation of the different module's interaction)
* keep backwards compatibilty with old telnet and rc modules. telnet is definitively a must have, i don't really know about rc.

==TODO==
* define all the commands and different features which will be needed.
* authentification method like this: Executing any script when user connecting via VoD link rtsp://server/test
