releases for packaging

[dvzrv]

Hey there!
Terrificly useful script! I'd like to package it for Arch Linux.

It would be awesome to have signed releases of the script, so packaging (besides a -git version) will become easier (and more reliable than latest HEAD).

Also, but this is a matter of taste, would it be possible to add a shebang? Otherwise I will have to do it during packaging. Something like

#!/usr/bin/python3

should be unixversally applicable.

There you go, for the -git package for now: https://aur.archlinux.org/packages/patchbook-git/
