Added python-docs for offline python documentation availability, removed
long-overdue polybar package which I have not been using for a couple of
months.
Package list is now a single tab separated list. That should make
several automations in the future much simpler.
The table is built as follows:
`Name Description Source Target`
with one line per package. Source denotes official repositories or AUR,
and target is kept for future potential of creating different
deployments per target automatically (e.g. different package list for
desktop and server, and so on).
There is an updater script `bootstrap/update_package_list.sh` which will
automatically populate the table, removing uninstalled packages, adding
new ones and (making its best attempt to be) keeping the selected
targets as they are.
The git commit hook comparing installed and committed packages has also
been rewritten to use the new table and be a little simpler overall.
Fixes#2.
