Reactivates the carousel of thumbnails on Twitter.
*Update 02/02/2013*: Twitter just changed the gallery... There is still no thumbnails slideshow... :/. So, my extension is dead, but thank you to all users!
A few months ago, Twitter had the (bad) idea to delete the display of thumbnails of the images in the gallery ... The "official" explanation is that they are an "experiment" of this new display, promising to return soon to this feature (see https://dev.twitter.com/discussions/9538) ... Unfortunately, it has been over 2 months and we are still waiting ...
Anyway, one day, I discovered that Twitter had simply "hidden" the carousel (and of course disabled the thumbnails download)! Indeed, from my personal observations, for that current system still work, they NEED this carousel ... therefore they cannot delete it!
