More Newspaper stuff

With some feedback from a few early testers, I've made a few adjustments:

• There are global and feed level settings for
• Having newspaper mode on
• Showing full content for items in newspaper mode, or just a short summary
• I've modified the way the items are displayed to provide a little more information
• If you have the global newspaper setting on, and you select a folder, you'll get newspaper mode for all feeds in that folder.

This stuff is only available in the dev stream; it's going to require documentation updates, and, in my opinion, more shakeout. It should be a really nice addition to the next release of BottomFeeder.
