Delay Profiles

This is to separate delays out to their profile (do we need a better name?) and choose preference of usenet or torrents and set delays independently.

I also changed the delays to minutes instead of hours so its more granular. I haven't done any UI work, removing old delays in profile or adding in the new UI.
I think that was Myth's reasoning as well. I like int better as it separates types and is the default when create a new list (one less thing to change). I'll settle on int here.
