Greed: Offline Support

I just released a new version of Greed, 1.1.2. The big update for this version is improvements in the offline support.

My goal with Greed was to make offline support as seamless as possible, where you wouldn't really notice it was in any sort of "offline" mode when it was. If it had a connection, it would try to keep things up to date, and otherwise read content from the SD card and synchronize it. That's why you see it do things like load articles from disk, then update from the network as soon as it has a chance.

Anyway, this version of Greed has several updates in it toward the goal of good offline support.

First, the "Cache All" function (accessible from the main menu) works better now, and is more conservative with memory. When you click "Cache All", you get all of the articles that can be downloaded, plus the content and attachments of any feeds you've explicitly marked for caching.

Second, Greed now takes a bit more of an explicit "offline" approach when a network connection isn't available. It sticks strictly with pre-saved content, and doesn't try to update automatically until it can do so smoothly. There's an option in the preferences that tells Greed to assume it's offline if the network connection is weak or slow. If you're in some kind of "1 bar" area or something, Greed will assume you're offline, and stick with the content saved to the SD card. You should be able to read feeds without disruption in areas with low-or-no-quality network access. (Provided you've downloaded them beforehand, obviously.)

For update operations such as "mark as read", "add star", etc., Greed takes care of that by queueing all such operations while it's offline, and then "playing back" those actions when a network connection becomes available.

Besides that, I'm also working on some feature requests (embedded browser, built-in media player, share with note), as well as new features for Cupcake when it finally arrives.

Suggestions and feedback are welcome as always.
