BREAKING CHANGES

Slack:

• slack_verification_token has been removed. Use slack_signing_secret instead. You'll find it close to where you find the verification token in the Slack admin pages, see https://api.slack.com/authentication/verifying-requests-from-slack#signing_secrets_admin_page.
• RTM is out, Socket Mode is in. What used to work with just a slack_token (if you still had it working), now requires both the slack_token and a new slack_app_token. See the docs at https://target.github.io/flottbot-docs/.
