add Login with Slack #nomads

show warning when non-user tries to sign in #wip

hide Slack login button if user is asked to connect Slack, because they will try connect Slack but then they're not logged in to site, they are then forwarded to login screen and see Slack button, they click it to login with Slack but because they've never connected their account to Slack it won't work, then they get angry in support #nomads

redirect users to Slack re-auth OAuth if Slack account not connected because we now need it to use IM #nomads

make postTripsToSlack use slack_access_token and use user's account to post arrival message instead of impersonating them as Slackbot APP #nomads

send login by email link when requested also to Slack as a DM so that people can login faster to the site if they're already logged in on Slack #nomads
