Notes on 6430-surveys-oauth2 @ 3900f65

• It's possible to migrate existing grants from OAuth1 to OAuth2, but I didn't do that. AFAIK it would be more efficient for all affected users (researchers) to revoke and re-authorize. But if it turns out someone does need this, it can be added.
• I didn't tackle the more generic GoogleSpreadsheet functionality here -- just the surveys -- but fixing the generic spreadsheets code shouldn't take much, now that the OAuth2 code is in place and there's the GoogleSurvey example to work from.
• Instructions for setting up the OAuth service are already on the wiki (Set up an OAuth service).
• I made some minor changes to the OpenHumans code in order to reuse the OAuth2 code that was already in place for OH. It could still stand to be cleaned up a bit more to simplify the admin's OAuth Service setup form, but I didn't want to turn this into an OH/OAuth refactoring story.

• Using OAuth 2.0 for Web Server Applications
• Migrating OAuth1 grants to OAuth2
