rewrite: the beginning

This a giant fuck-you to myself while I have nothing (actually, tons of
things) to do in a hospital.

* The giant screens of preprocessor code are gone, they always sucked,
  fuck them.
* Switched everything to the "boxes" interface as the only one
  remaining.
* Restuctured things in aes/ so that the files they're in make at least
  a little bit of sense.
* Removed a bunch of cruft and prematurely generic code.
* This is half-baked at best: I just made sure that the tests pass. A
  lot of cleanup awaits.
