Greed2: Notifications

I just pushed an update to the Market for Greed 2, this one containing more complete notifications logic.

You should now be able to do the following:

• Turn notifications on and off (in the preferences).
• Get notified on any updated feed, or specific ones (in preferences, and selecting individual feeds' "light bulb" icon).
• See a little green highlight on the left edge of feeds when they're updated since the last time the unread counts were checked.
• Set Greed to notify you with sound, vibrate, or just the notification icon.

Next up, some updates to the article viewer, and more options for managing feeds and articles.
