0.5.1 release

Created by: jamierytlewski

Curious as to when the 0.5.1 release is going to come. I see that the documentation that is listed here http://rdoc.info/github/intridea/oauth2 does not match what the current version when you download the gem. I was using token_url and assuming that the token method was post by default. I was racking my head trying to get it to work until I realized the documentation does not match my current version, but matches the rc1.
