Persisting Selected Authors

A pretty big change here. I've been able to figure out local storage,
for simple things like checkboxes. I've decided to put them all into an
array (or really a JSON string) and just index off that way. I don't
think it's very efficient, but I'm going for functionality before
elegance. At the moment, it works. Now I need to make it pretty, then I
can make it optimal.
Commenting the dynamic checking

I needed to add some comments and cleanup code to the bit that
dynamically checked the boxes from local storage.
CSS Formatting

Just eyeballing it, it looked like some of the formatting of the
checkboxes wasn't quite right. I found some code on Stack Overflow
(http://stackoverflow.com/questions/306252/how-to-align-checkboxes-and-their-labels-consistently-cross-browsers)
on how to align checkboxes better.
