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 didn't do that because there might be multiple delays that are the same on different profiles (since we forced that behavior to each profile). This also makes it obvious it was created for a delay (and unlikely to collide with something already created). A tag telling me the delay is better than telling me it was created for HDTV 720p I think.
