Make official Snap package and support it

[soumyaDghosh]

I have been using flatpak in fedora, I kinda liked and disliked it. But my workflow is in Ubuntu and Ubuntu doesn't really supports the flatpak well. The ppa available for Ubuntu and Debian is atleast 5 gens behind. It'd be much better, if u could make a snap package also and support it. I read the issue #26, I'd like to reopen it too. It's not compile able anyways in ubuntu easily. Also, if you can make a deb file, that'll also help instead. We have a project called Pacstall. We will serve the app via there.
