Title: Don't include request parameters in oauth signature if not URL encoded

This fixes a deviation from the spec regarding which parameters are included when calculating the OAuth signature. For requests with parameters in the body, they should only be included if the request's content-type is "application/x-www-form-urlencoded". See RFC 5849, Section 3.4.1.3.1. (Parameter Sources).
