Script Summary: Append a retweet button to the end of each twitter entry, original script by Ziru, updated by me.
I've taken Ziru's script (http://userscripts.org/scripts/show/26500) a step or two further by implementing AJAX-enabled retweets. When clicking the "ReTweet" button, a modal dialog pops up, via jQuery and Eric Martin's SimpleModal script (found here: http://www.ericmmartin.com/projects/simplemodal/), and you can retweet the message from the dialog.
It's stable as-is, but more updates will be needed.
