"parse_setup_ini" more accurately describes function

also test if commenting out the "if dists" block breaks things (not yet)
remove dead wood, add docstring, de-globalize
fix broken help, de-globalize
collect globals together, remove dead wood
bump version, remove old comments, tweak help

Move general reverse engineering comments out of function so I'm more
likely to see them (and thereby not do the same work twice!)
clean up and docstring split_ball, pep8 rest of parsers
clean up and docstring post_install, pep8
doc & pep8 rest of Getters (more docs needed)
