- requests is now the default url/http library, thanks to Mike Helmick
- Initial pass at a Streaming API is now included (Twython.stream()), due to how easy
    requests makes it. Would actually be sad if we *didn't* have this... thanks, Kenneth. >_>;
- Return of shortenURL, for people who may have relied on it before.
- Deleted streaming handler that existed before but never got implemented fully.
- Exceptions now prefixed with Twython, but brought back originals with a more verbose error directing
    people to new ones, deprecate fully in future.
- Twython3k now has an OAuth fix for callback_urls, though it still relies on httplib2. Thanks @jbouvier!
- Added a list of contributors to the README files, something which I should have done long ago. Thank you all.

whatever query parameter arguments you read on Twitter's documentation (http://dev.twitter.com/doc) gets mapped
as a named argument to any Twitter function.
For example: the search API looks for arguments under the name "q", so you pass q="query_here" to searchTwitter().

Doing this allows us to be incredibly flexible in querying the Twitter API, so changes to the API aren't held up

"""
A Streaming API endpoint, because requests (by the lovely Kenneth Reitz) makes this not
stupidly annoying to implement. In reality, Twython does absolutely *nothing special* here,
but people new to programming expect this type of function to exist for this library, so we
provide it for convenience.
Seriously, this is nothing special. :)
For the basic stream you're probably accessing, you'll want to pass the following as data dictionary
keys. If you need to use OAuth (newer streams), passing secrets/etc as keys SHOULD work...
username - Required. User name, self explanatory.
password - Required. The Streaming API doesn't use OAuth, so we do this the old school way. It's all
done over SSL (https://), so you're not left totally vulnerable.
endpoint - Optional. Override the endpoint you're using with the Twitter Streaming API. This is defaulted to the one
that everyone has access to, but if Twitter <3's you feel free to set this to your wildest desires.
Parameters:
data - Required. Dictionary of attributes to attach to the request (see: params https://dev.twitter.com/docs/streaming-api/methods)
callback - Required. Callback function to be fired when tweets come in (this is an event-based-ish API).
