Subject: WIP: restructure

A stupid attempt to reduce code duplication led me to believe that all
the scripts could use _a bit_ of refactoring.
This is going to be a major pain (factoring out all the things), which
I'll take gladly.
All the links and usage examples are broken right now, but nobody cares,
so whatevs.

+'''Download & build Boost on AppVeyor.
+
+This is similar to build.py, but auto-fills some parameters for build.py from
+the AppVeyor-defined environment variables.  This script is rarely usefull,
+since AppVeyor images come with lots of pre-built Boost distributions, but
+still.
+
+Boost is built in C:\projects\boost.
