Remotecontrol throws verbose exception info to console whet it can't bind to the default port

[avar]

Remotecontrol will throw an exception like this to the console:

loading remotecontrol

A simple 1-line message saying it couldn't bind to the port would suffice, but I couldn't find a way to do that by catching the exception and throwing something that didn't print out the full backtrace but stil didn't make the run() method run.

fix #4062 - remotecontrol prints stack trace when it can't bind to the default port
