* initial stuff for oauth2 login, fails on: * login button on the signIn page to start the OAuth2 flow and a callback for each provider Only GitHub is implemented for now * show login button only when the OAuth2 consumer is configured (and activated) * create macaron group for oauth2 urls * prevent net/http in modules (other then oauth2) * use a new data sessions oauth2 folder for storing the oauth2 session data * add missing 2FA when this is enabled on the user * add password option for OAuth2 user , for use with git over http and login to the GUI * add tip for registering a GitHub OAuth application * at startup of Gitea register all configured providers and also on adding/deleting of new providers * custom handling of errors in oauth2 request init + show better tip * add ExternalLoginUser model and migration script to add it to database * link a external account to an existing account (still need to handle wrong login and signup) and remove if user is removed * remove the linked external account from the user his settings * if user is unknown we allow him to register a new account or link it to some existing account * sign up with button on signin page (als change OAuth2Provider structure so we can store basic stuff about providers) * from gorilla/sessions docs: "Important Note: If you aren't using gorilla/mux, you need to wrap your handlers with context.ClearHandler as or else you will leak memory!" (we're using gorilla/sessions for storing oauth2 sessions) * use updated goth lib that now supports getting the OAuth2 user if the AccessToken is still valid instead of re-authenticating (prevent flooding the OAuth2 provider)
