Flatpak distribution

[starkers]

I would like to open the conversation about getting a flatpak build of this uploaded to flathub please

I've found some documentation regarding how to build this in flatpak and I've wrapped a few electron apps into flatpak before. So I'm very happy to volunteer some time to teach anyone who is willing/able to integrate this here.

My goals as a multi-distro linux user:

• install this via flathub (not via manually downloading and chmodding AppImages)
• have automatic updates available

refs:

• https://docs.flatpak.org/en/latest/electron.html
• https://flathub.org/home
• https://github.com/starkers/flatpak-bitwarden <- example "lazy" way to build a flatpak from an electron native AppImage (not ideal because of lack of chrome sandbox, there are better ways now)
