Title: Show tagging for folders and accounts that have unseen messages

This implements issue 362 (http://code.google.com/p/k9mail/issues/detail?id=362)

Newly-downloaded unread messages are flagged as "unseen", increasing a separate counter independent of the "unread" counter. This counter is shown as a separate chip in the folder and account lists (using an "eye" for the chip right now - better ideas welcome). When the folder is opened in the UI, the "unseen" count is cleared, as you have now seen those messages in the folder. If you've used Thunderbird before, this is feature parity with the blue highlighting on folder and account names that it does when new unread messages are downloaded.

I still have one open issue on my branch (https://github.com/justdave/k-9/issues/3) but it's minor, and as this contains database changes I wanted to try to get it landed before anything else hits that changes the DB.
