Bug 800402 - [email] UI: Show the number of unread messages in the message-list header after the folder name

This console.log as it exists should/could probably go away.  I'm assuming it was temporary debug.  One "trick" I like to use for temporary debug is to completely avoid indenting them.  That way they stick out like a sore thumb and most reviewers should yell at me to help me out :)  However, as code formatters become more aggresively present in our editors, maybe this strategy won't work out.
