make authentication tokens last a week

[jshslsky]

I'm going to include this in the stuff I'm working on. Already pushed the change at mschulkind/shim@09284da and it will eventually make it back to this repository.

Well, I actually changed the authentication token, not authorization token. Did you really mean authorization token?

[jshslsky]

It's the authentication token. I updated the issue title.

For the authorization token, it will have to be programmatically refreshed whether the timeout is 30 min or 1 week (dependent on the third-party we are OAuth-ing with).
