limechat.net/mac/ website gets insecure warning when using firefox. Might want to switch to https with letsencrypt

[Danrancan]

Probably not too big of a deal since there are no downloads being made on the limechat homepage, but when I navigate to the homepage in firefox, i get an insecure website warning. To the average noob, they might not understand that this doesnt matter if there are not downloads happening on the homepage with potential for a mitm attack. However, its also extremely easy to get free letsencrypt certs for the homepage. I would recommend it, as it would make things appear to be a bit more professional as well. Just wanted to point this out.
