in OAuth 1, Content-Type header check is case sensitive

[elachuni]

When signing an OAuth1 request with Content-Type 'application/x-www-form-urlencoded' and a body, the header needs to be exactly "Content-Type".

The check oauthlib performs is case-sensitive, so neither "Content-type" nor "content-type" work and oauthlib will raise ValueError("Body contains parameters but Content-Type header was not set.") as if there weren't a content-type header at all.

Yea, it's been in the back of my head to fix this but never got around to it. Will sort something out tonight, thanks for reporting!

np, thanks for the quick response (and for oauthlib)!
