BOM Updated for PewPew Lite

Published on 2017-07-24 in PewPew FeatherWing.

Since I’m starting with PewPew Lite, I updated the bill of materials to reflect that. the non-lite version will be done if the Lite version catches on — otherwise I will switch to D1 Mini as the development board.

I also added a link to the project’s repository, and added a license (it’s CC by-nc-sa for now). The work on the tutorials is coming slowly.
