Title: Better content-type detection and unicode fix

Better content-type detection for request.auth.OAuth1, fixes [OAuthLib #38](https://github.com/idangazit/oauthlib/issues/38). All requests with files are now treated as multipart and r.data is not included in the signature creation.

Small fix to a UnicodeDecodeError during httplibs concatenation of the unicode Authorization header and file data.
