Title: Adding comma (,) as a percent escaped character

since it's in the reserved words per the RFC.

Since we don't share AFPercentEscapedQueryStringPairMemberFromStringWithEncoding outside of AFNetworking, but AFOAuth1Client depends on having the _same_ escaping done, there will be another pull request there shortly
