Twit 01 android dev tweets

Performs OAuth using the "signpost" library. Retrieves a number of #AndroidDev Tweets from twitter and displays in a custom list. All REST api requests are done via AsyncTask and apache http client.
be careful with the name here, currently this class only handles requesting android dev tweets. I would expect a manager to do a few other requests and then in that case you would be better off using the factory pattern to build `Request`s
