theme manager fixt

the one big impediment to publishing the source for this blogger is finally fixt. the theme manager seemed to work properly, but in reality, i was just faking it to make it work while i figured out what to do. the problem had less to do with a bug, and more to do with how to write the theme manager properly, but now it's actually fixt... which means i'll be able to publish the source code within a week or so.
