Linux support

Adding support for Linux.

I would be willing to also create an accompanying Flatpak release (that's the modern distro-agnostic packaging format for Linux) on Flathub, if permitted to.

This PR also upgrades a number of dependencies, as it was necessary for Linux support.
However, all breaking changes have been taken care of and care has been taken to make sure everything works.

Awesome work, thank you so much!

Thanks for being so quick to review this! :)
Would it be alright for me to create a Flatpak for this? I would need to pull from Releases somewhere — either I'd compile the necessary Linux builds for you and ask you to host them in Releases or I would host them in my own repo.
Either way, if you'd be alright with me publishing the Flatpak on Flathub, should I use "TimeCop" as the name or something like "TimeCop (Unofficial)"?

I'd be happy to have you create an official Flatpak for this. I would like to update all the releases stuff (it's quite out of date) including versions, etc. I just haven't been able to get the time lately unfortunately.

In that light, would you like to be added as a contributor to the repository so you can manage some of those things more quickly and directly? I wouldn't be expecting you to take on full responsibility for everything, but you're welcome to keep moving things forward as you see fit.

@hamaluik That'd be great!
For me, it's also a question of when I find the time, but I'd love to e.g. bring the app to Linux, tag a release in order to bring the app to F-Droid, or make community translations possible via Weblate.
With things that I don't find clear-cut (e.g. a proposed UX change), I would wait for your go-ahead.

@hamaluik Thanks for adding me!
