2147 - starting to split edit.mu into layers

edit.mu is now over 9k lines long. Only 2.6k of them are code. Plan:
chunk it into multiple files inside say an 'edit' directory. Then you
can run it with:

  $ mu edit/*

I also want to be able to test just a few layers:

  $ mu edit/00[1-5]*

When I try to chunk it into files, the first issue I run into is that
before/after can't refer back to previous layers. Solution:
transform_all at one shot after loading all files.
