Need smarter "Popular" factor

[bcrisler]

When a user goes to "Browse Media>Popular," it appears that the system is basing "popular" on nothing more than an aggregate play count, which means that the popular list is dominated by very old videos. I'll suggest a bit more complex calculation that would weight the list toward newer content.

Something like ...

(play count last 3 days * 5) + (play count last 7 days * 4) + (play count last 30 days * 3) + (play count last 356 days * 2) + play count all time

We will have to update the mediaView php script to remove the popular play count from old videos
