New: user-to-user invitations

Good news:

If you’re a current Brizzly user, we’ve enabled invitations in your account: look under the “Trends and news” bar in the right-hand navigation column. Go tell your friends how much you love Brizzly (and we’ll tell ours how much we love you).

Also, we made a new introductory video, which is in HD and is a bit more detailed and easy to see than our previous video. It also covers our new photo upload feature (and features some original music composed by yours truly).
