Subject: Rewrite mktags.sh to MakeTags.py

This makes tags for all third-party dependencies, and uses universal-ctags
instead of fast-tags. It's so nice having tags for /everything/. It's also
pretty fast, and caches the result for third-party deps anyway.

Oh yeah this also added an explicit list of third-party Python packages. I need
to filter the entire pkgset down to just the ones I'm using in order to make
tags for them.
