Methods that handle commands are still in internal/cmd, but the commands themselves are now in internal/commands. Commands should import internal/cmd and call Register() to be added to the commandlist.
Furthermore, this commit adds the requests file, with a genUbusRequest() method.
Some channels to handle connection/disconnection requests from commands. Moved the in/out channels to internal/setting.
Also added a connect and disconnect command. The code keeps getting worse...
