Fix ordering for shows with 500+ episodes. Now it works for up to 500k.

The "Downloads" ordering works by taking the percentage of episodes downloaded vs non downloaded, but it needs to transform this into a integer, previously it was being multiplied by 1000, but that's not enough to sort shows with 500+ episodes, like Simpsons, SNL, etc.

So I changed it to multiply by a million, that way it will work for up to 500k episodes. That should be enough until we evolve into beings that can watch multiple shows at a time while absorbing all of it.
