Extend bild to nix targets properly

Also had to capitalize some stuff, and move some nix files around and rename
the metadata directive from 'exe' to 'out' because that just makes more sense,
and fix some compiler errors. But now bild treats both nix and hs files as
buildable things. So that's cool.

One interesting example is Biz/Pie.{nix,hs} - I can either create a dev build of
the hs file with ghc, or I can create a fully-encapsulated nix build. Its nice
to have both options because a dev build with ghc takes half the amount of time,
and I can rely on my locally cached hi and ho files. I think this shows the
power of bild, but also can be a somewhat subtle thing.

The issue really is with the separate command calls in nix builds vs dev builds.
I figure there are a few ways to fix this:

1. Try to use bild inside the nix rules. That could be interesting, but could
also lead to some weird behavior or worm holes forming.
2. Extract the command line invocation into a separate file, some kind of
really simple template that gets pulled into both programs.

It is important to consider that in the future I might want to have bild do a
module-by-module nix build of programs, but I'm not sure how that would effect
my choice here.
