Title: Got incremental make working for document generation.

Incremental make wasn't working because ```commands.tex``` (command usage help) was regenerated each time. Now it isn't regenerated unless the command help text has changed. To do this properly I guess the Makefile should really check the source command scripts in the bin directory, but this works well enough.
