Has this feature been discussed and generally agreed?

Issue has been mentioned multiple times in discussion groups and on Jamulus facebook groups, but afaik not on github.
The given solution is always to edit the ini file (or even to delete it!), but I don't think this is very user friendly.

Describe the solution you'd like

Add an option to delete servers from the "Server" and "Custom Central Server" lists.
i.e. right-click server and select "Remove from list"

Describe alternatives that have been considered

Until now users have to edit the ini file to clean up their server lists.
