media loader needs updating

This is a great idea and much needed. Unfortunately the media loader is still using the old (pre-3.5) model and has no search function. The only way to filter images is by date, which might work for a blog. I tried it on a website with 1000+ images, about 800 of which were uploaded when the site was built, and was faced with browsing through over 80 pages of 10 thumbnails each to try to find the image I needed. Would love to see it brought up to date!
