Release v1.11 proper

[shazow]

We have some pre-releases, should just cut a full release. https://github.com/shazow/ssh-chat/releases

Should investigate/fix #404 before doing a v1.11 release IMO. Help appreciated. :)

@shazow I would say - release and place a warning that there is a potential issue with whitelists, asking people to validate or dismiss the claim.
