Please provide an Element AppImage for Linux

Providing an AppImage would have, among others, these advantages:

• Applications packaged as an AppImage can run on many distributions (including Ubuntu, Fedora, openSUSE, CentOS, elementaryOS, Linux Mint, and others)
• One app = one file = super simple for users: just download one AppImage file, make it executable, and run
• No unpacking or installation necessary
• No root needed
• No system libraries changed
• Works out of the box, no installation of runtimes needed
• Optional desktop integration with appimaged
• Optional binary delta updates, e.g., for continuous builds (only download the binary diff) using AppImageUpdate
• Can optionally GPG2-sign your AppImages (inside the file)
• Works on Live ISOs
• Can use the same AppImages when dual-booting multiple distributions

Here is an overview of projects that are already distributing upstream-provided, official AppImages.

Example Riot AppImage: https://bintray.com/probono/AppImages/Riot/_latestVersion#files

Made using: https://github.com/AppImage/AppImages/blob/master/recipes/meta/Riot.yml

electron-builder has native support for generating AppImages, so it should be very easy to do.

If you have questions, AppImage developers are on #AppImage on irc.freenode.net.

@srevinsaju: great, thanks! i think it would be worth advertising about your appimage on #twim:matrix.org.
