Completely broken on iOS 7

For whatever reason, iOS 7 doesn't seem to like this code one bit. It doesn't crash or anything, but for whatever reason the resulting attributed string, despite containing all the right text and attributes, doesn't draw.

My hunch here is that maybe the keys used to identify text attributes may have changed in iOS 7, but I'll look into it further this afternoon.

This does highlight the fact that font handling needs to be better. Right now to change the font for a given scope, you have to include at least the font name and size, which is more verbose than you'd want to be if you just wanted it to be italic.
