Gif togglify for Diaspora*

Append a toggle feature to all animated gifs inside the Diaspora* stream simulating the animation start/stop. A bit rough and intrusive (all images are parsed to check for gif header and animation frames) but useful if you're annoyed by repetitive animations in the stream.

N.B.
Still in development, beta-test version with some unresolved issues.

What is Diaspora*?
Diaspora* is an awesome, decentralized, free and open source social network.
