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.
ahhh I see what your doing. :x: you've got a very mutable array list which causes side effects in others classes.

You could solve this easy peasly by moving all of the tweetlist logic into the adapter and have a `update()` method on the adapter!
