Search for videos in the dashboard

Up until now, you could only keep track of your videos (or videos you're interested in) by adding them to your favorites list. While this is enough in most cases, I've got comments from people who wished they could search for videos in the dashboard.

So I've added this option. Now there's a "Search for video" area in the dashboard that's similar to the one found on the main page. Note that this search will search all languages and (of course) can return videos that are not yet ready for viewing - that's what the dashboard is all about.
