Start releasing again

TL;DR: This release bundles all changes to the master branch over the last year into version 4.1.

Hey everyone! 👋

I've been taking a break from this project for a while. Didn't plan for it to take this long, but life happened. Slowly getting back on the horse now and hope to not fall off it again for a while 🤞 😅

A huge thanks to @pkishino 🙌 🙇 He has kept the project going the past year, and even before then he has been the number one contributor (myself included) for a while now.

Making releases has been my responsibility, and it's now over a year since the last one. High time to make some new ones. So here's the plan:

• Creating this 4.1 release as a marker as it's been too long already
• I'll merge the changes from the dev branch and include them in release 4.2
• Next up I think it's time to bump the Ubuntu base image to get a newer version of Transmission, that should be 4.3. But time will tell.
