Provide ways to rename "/Cloud Drive" "/Inbox" and "/Rubbish Bin"

[gissehel]

The strings "Cloud Drive" "Inbox" and "Rubbish Bin" are "created" by the client, they don't really exists as real node. The default values are those because it's the name in the web interface, but having a way to use /Root instead of "/Cloud Drive" may be seen as more "command line user friendly".
