twitter: show tweeted media as thumbnails

Tweeted photos are directly integrated in the stream.
The alt attribute in the item.phtml had to be modified to reflect the
changes made to the title (having <a href> links in the alt attribute
is not allowed, so they must be removed).
make thumbnails bigger

Bigger thumbnails make Twitter photos more useful.

Note: this must be changed for mobile devices

Having been enlarged for the Twitter media support the thumbnails are
now resized per css to match the screen width again.
