Add org key for slack team name

[patcon]

Seems that most every brigade has a slack team. Would be great to keep track of this in the API

In particular, I'm interested in creating a service that works a little like this:
https://github.com/davidkassa/hubot-slack-relay

The idea is to make slack a little bit more like IRC, where you can easily jump into someone else's channel and start talking and sharing information. Would be great if a central service kept track of all the authorization tokens, and a bot script allowed users to send receive messages between teams :)

Hm. Or perhaps it should just be slack_url, and then people could either link the login (https://civictechto.slack.com/) or link to an invite page if they've chosen to host one (http://civictech.ca/slack/).

Great idea. Here's how it could work:

• In https://github.com/codeforamerica/brigade-information add an optional slack_url attribute to the organizations.json docs.
• Add the slack_url attribute to the Organization model
• Write a migration for this change. I think its python app.py db migrate
• run_update.py should automatically pick it up the new info, but double check here
• Add some tests that the attribute is getting picked up and added.

You could do the same thing with Twitter handles too.

Great! I've got it started, but I'll have to investigate testing tools in python later
