1. Fixed the code to handle content_type missing from headers. instead of defaulting it to JSON, now trying to load it to json, xml, or then simply returning the content. Code was failing when the content_type was missing but the content was not of json type.

2. Handled the case where an exception was raised when the token URL responsed in a code other than 200 or 201. Instead of raising OauthException now returning the error code in a dictionary so that it can be handled or displayed.
