added source-files-list to populate-html-template. kindof dislike having
so many variables passed to a function but i also kindof dislike global
variables; not sure how to make this prettier yet. but this solves the
bug i introduced in my last commit where the nav links were broken when
used as a githook.
- removed old comments
- moved todos and nice-to-haves into the README.md's todos and hopes
- changed gobally mutated variables to be global constants. originally
these were mutated because the code was structured differently, and
allowed an option argument, specifying which bare git repo to use, but
i removed that, and forgot to remove and change the cruft
