Saving archive layout options had stopped working.
Fixed a few more instances of unset variables being used. For better or worse, I've made it so that if a theme is not set, the page outputs a warning. Previously, it would either display a completely unstyled page or a blank page depending on... I don't even know what. At least this is consistent, and explains what the problem is.
Sorry about the seemingly redundant commits here. GitHub is silly xP
