added a Makefile, so either `make` or `./make` can be used for most tasks

`make` doesn't always work, like when the user tries to do certain types
of CLI args, but it's handy to have as a convenience sometimes.

What works:

  - make
  - make clean
  - make hank boost
  - make me a sandwich

What doesn't work:

  - make foo --bar
  - make foo BAR=1

The `make` program eats some types of arguments.
