Add CSS class to Twitter div, or add option to disable it

I'd like to not show the "Create a Twitter message..." part after the URL is shortened. There's currently no class on that div so it's harder to hide it with CSS. It'd be helpful to have that added, or add a disable option to the Settings.

I went in and added the class to the .module file myself, but I know that's a hack and should be formally requested here. :)
