enable auto account creation on oauth login
Would be great if one could create an account just from GitHub login. So UX would be:
- Click "Login with GitHub"
- Allow to use user data from GitHub
- You are logged in with your new account
It uses the e-mail github has and you can reset your password with that address if github would disappear.
Not sure if Gitea supports this workflow.
Follow up to #225.
