Redirect isn't caught #28

This api implementation does not respond to redirects very well. For example, lets say you have a site that redirects all traffic from http://ubersmith.site to https://ubersmith.site and the client uses the http://ubersmith.site url. In my case, this api responded with messages indicating missing parameters.

It appears the requests module redirects with a GET instead of a POST if the webserver responds with a 301 or 302 but redirects correctly if a 307 is returned. However, the 307 is not implemented often by web admins.

The result is that the contents of the post are lost and the webserver responds as if the method is valid but with missing parameters.

I think the solution is simply to add "allow_redirects=False" to the requests.post in the _send_request method in api.py. At that point we should check the response - if its a 307, go ahead and post to the new url, otherwise, respond that the webserver attempted to redirect in manner that is not supported by ubersmith.
