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.
Yeah, kinda hacky, the only valid reliable way is via another property, which would help in the UI too, does that make sense?
