Allow proxyAddresses in classes and projects

[kiarn]

• Add --set-proxy-addresses to sophomorix-class and sophomorix-print
• no add-proxy-addresses or remove-proxy-addresses yet
• added info to console-print in GROUPS

Thanks for the PR, it seems to work. However I think it's necessary to add the options --add-proxy-addresses and --remove-proxy-addresses in order to have a full management of the proxyaddresses :)

yes, you are right. I was too lazy to implement it.
Please keep the PR open/not closed until I get to implement it?

Thanks. I think there was another reason for not implementing it. I guessed that jeffbeck was about to refactor the whole thing, not sure.
