Updated Twitter Fixer

I've updated the twitter fixer user script so that now it doesn't cause some twitter information to be impossible to view. Previously if you clicked on a tweet or a twitter user to get further details then the box which contained the further details would be hidden on the right side of the screen.

This new version fixes that issue by presenting it to you in (almost) full screen, in the middle of your display.

If anyone sees any other issues then please let me know via a comment.
