Move promotion below description

[augustskare]

First, thanks for creating and hosting NRSS! Please disregard this change if you don't agree.

I fully understand that you want contribution/donations, my only issue is that now with the promotional text before the original description it's harder to get an overview of what each episode is about (in some players I guess).

Hopefully people that care about the description read your promotion regardless if it's first or last.
