Get rid of obsolete Twitter API call and update Rakefile require's to work in Ruby 1.9

Removed the previous Twitter Anywhere call and replaced it with a timeline for @bmoreonrails.

The previous requires on lines 3 and 4 of the rakefile didn't work with Ruby 1.9.  Prepending ./ should let them work on both 1.8 and 1.9.

Ali helped. And the widget is linked to his account, so he has the ability to modify/delete.
