Add parameters in OAuth1 callback

[quangbuule]

This solves #81.
For instance: Twitter auth callback contains user_id that can't be found in any other APIs.

Thank you
I can develop from now but by just watching, I think demo code must be updated too by adding parameters into callback before "in"
https://github.com/dongri/OAuthSwift/blob/master/OAuthSwiftDemo/ViewController.swift

And If you can readme.md too by adding parameters also to oauth1 example

in your next commit message add : fix #81 for auto close (maybe this work also with PR title)
