Release new version

@dblock Could you cut a new gem release? :)
Would love to use the new users.lookupByEmail method.
Thanks!

I ran ake slack:api:update and got a failure in a patch, so looks like this is a bit more work. Care to fix that and make a PR? I can cut a release after.

Seems like the method parsing of https://api.slack.com/methods/chat.postMessage failed, all the arguments were removed: slack-ruby/slack-api-ref@3085544#diff-294069ad8348d4365db2a6446789d0a5
I'll have a look and try to find out what's wrong.

Slack changed the format of the method doc pages slightly (removed a <p>), this is why all arguments were removed in the commit mentioned above. Fixed in slack-ruby/slack-api-ref#27

[dblock]

@manuelmeurer Now that slack-api-ref is fixed, make a PR here with updates. It's slack:api:update and a proper CHANGELOG. Thanks!

[manuelmeurer]

Done: #196

@manuelmeurer Want to do the release? What's your rubygems email?

[manuelmeurer]

Sure, it's manuel@krautcomputing.com

[dblock]

You've been added. Please follow https://github.com/slack-ruby/slack-ruby-client/blob/master/RELEASING.md and close this issue once it's done. Thanks!

[manuelmeurer]

Ok thanks! Should the next version be 0.11.1 (noted in the changelog) or 0.12.0? Probably the latter, since we added at least one new method, right?

[dblock]

API changes that break things need a major increment, but not additions, so 0.11.1 is fine IMHO

[manuelmeurer]

Done! ✨
I missed one update in the README since I misread RELEASING, so I fixed the wording. Hope that's ok!
