Allow to use Proc for generation of state

[avokhmin]

By #94

Sometimes need to use own value of state.

For example: you can use own encryption for send extra data in state (expires, ...).

Also It can be useful if some providers do not support callback_params in callback_url

@avokhmin The only persons that can actually publish a new gem are listed on the gem page: https://rubygems.org/gems/omniauth-oauth2 , it's @tmilewski @sferik and @mbleigh Could some of you take care on this?

[avokhmin]

looks like need to wait next 3 years... 😢

[mbleigh]

@BobbyMcWho since you're maintaining other parts of OmniAuth, are you up for maintaining omniauth-oauth2 as well? I'm not in a position to continue managing releases for this gem.

[BobbyMcWho]

I'd be happy to help as time permits, I unfortunately don't have a ton of time to devote to open source lately 😔

[mbleigh]

@BobbyMcWho you now have publish rights on omniauth-oauth2
