Title: Add {{isLoggedIn}}

I've noticed lots of re-render issues on SO such as this one:

http://stackoverflow.com/questions/14783809/content-wrapped-in-currentuser-re-rendering-when-user-updated

I've added in a helper and the docs so that the {{isLoggedIn}} returns a true or false, independent of whether any user variables are updated, and it shouldn't force a redraw.
