What's new:

* When you download videos from YouTube (whether by search or in a YouTube feed), we get an MP4 rather than a FLV, if it's available. The video quality of the MP4s is much higher.
* Updated translations in lots of languages.
* We've updated the linux version to Mozilla 1.9.
* We've updated VLC on Windows to 0.8.6f (security fix).
