Move/delete non-core modules

[hamnis]

This part of the Oauth2 spec was never finalized and we should remove it.

I think its probably a good idea to prune some of these modules we've considered to be "outter rim" modules into separate repositories that maybe could be maintained separately. I'm a +1 on this. I'd think the modules that are closer to what the core of unfiltered should be the only ones that belong in this repo.

@softprops Which specific modules are you referring to?

The initial list of non-core modules I think is:

• mac
• oauth
• oauth2
• json4s

Maybe:

• agents
• websockets

That sounds like a pretty good approximation to me
