Test hashtags and tagging...

So, we should have a couple of new features... first, hashtags #CoolStuffLikeThis

In theory, this will tag something for a global query.  When you click the hashtag it should return all posts with the tag.

And second, individual tagging @Mul21... this should alert the tagged person to the post.  For users with a space in their username you need to include " after the @ sign and at the end... like this:  @Mr MattM (@ "Mr MattM" without the space following the @ sign)

@Mr MattM this is #cool

What about the new toolbar that says I have 6 notifications?
