Offer a flatpack to have a universal linux package

[thalskarth]

Hello, I saw in the main site some .deb, .rpm, etc as offical instaler packages for linux but this usually works only on some linux distros and may cause dependecy conflicts. Also que archlinux AUR package requieres to recompile the libjs dependency from time to time to work.

Would it be good to have a faltpack package, this will solve the dependecies conflicts and also give an universal package wich will work the same on any distro like Fedora, Arch, Manjaro, Suse, Mint, etc at the same time.

A Flatpak is now available from Flathub.

Just tested it out and it works. Wanted to mention that users may need to use flatseal to give yacreader permission to see the directory that contains their manga. This is a flatpak issue though. Just a heads up before someone files a bug about this.
