the twitter sign is a little confusing, with the pins and what not.

use https://oauth.io/

OK, moving of oauth to oauth.io is done, commit is pushed to refactor/oauth branch. Will merge once I can get oauth.io to play nice with codebird.

Potential issues

• You need an oauth.io account to use it(duh) I've made an account there, do you want to make another account for the app? or would you like me to pass that onto on of you guys?.

I think it'd be better to just pass that on to the team.
