Bump the master branch so the project doesn't get dismissed as obsolete

[Giszmo]

I was looking for Multi Vendor Multi Signature wallets and almost missed that

goatpig bump version and update changelog 1d02a66 on Dec 23, 2018

on the repository's main page doesn't mean the project is obsolete. The dev branch is active and 1142 commits ahead of master.

I would suggest to maybe point to that fact with an edit of the Readme.md on master ;)
