[Feature Request] OAuth Login

[leogott]

I use OAuth with some sites, to e.g. use my github login instead of creating a new password with examplesite.

It would be pretty useful to have a secret like
file: Account/examplesite

oauth: user @ github dot com

and upon invoking gopassbridge, ideally the oauth button being highlighted/pressed, but I'd be fine with a popup "Hey, gpbridge here, use OAuth with Github and user :3"

like at the simplest just display the content of the oauth json-key

thanks
