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.
this should be

`return collection != null && collection.Empty();`

right now if I pass in something that isn't a list like an int will cause the validation to pass.
