Samtec Q Strip/Q Pairs, Basic Blade & Beam, Razor Beam, and mPOWER connector generators

I wrote this script (and YAML file) to generate nearly every common vertical configuration of the Samtec Q Strip and Q Pairs connector families. It was developed as a result of my work in the kicad-footprint-library. I tried to make the code and data files as clean as possible so that they can hopefully be used as a solid starting point for future contributions.

This PR also contains a hack to work around #395. This was necessary in order get the the script to run.
