Begin supporting run

I'd like to be able to just call `run file.py` and have a program DWIM. I'm
working on run as a step in this direction. Define a simple configuration that
maps file extensions to template strings where "$file" is replaced with the
argv[1].

It basically works but there are outstanding TODOs. See the README and source
code for more information.
