[rqt_remocon] ambiguous ROS_HOSTNAME error

[stonier]

When ROS_HOSTNAME is not set, you get an error printed in the shell.

[error] Rqt Remocon: 'ROS_HOSTNAME' 
[debug] Interactive Client : initialised
[debug] Interactive Client : Connection Details

1. The gui doesn't abort
2. This is not actually an error if you are connecting over localhost

To fix:

Just move it to a warning. Would be nice if the gui had some way of showing what the ROS_HOSTNAME/ROS_IP settings are.

• I will change the error into warning if user does not set ROS_HOSTNAME. In this case rqt remocon use localhost as ROS_HOSTNAME
• I think that it is good way to use widget object name to show ROS_HOSTNAME/ROS IP. For example,

Role Chooser - ROS IP [http://localhost:11311  / ROS HOST NAME [localhost]

[stonier]

I think you mean:

Role Chooser - ROS_MASTER_URI [http://localhost:11311]  / ROS_HOST NAME [localhost]
