AppImage builds?

Would love to use Synapse as an AppImage.

AppImages run on all Linux distros, it doesn't require installation or root (just make it executable and run it), it's portable (all packed into one file) and it's been in use for over a decade.

It would enable you to not need to package both DEBs and RPMs, and negate the need for any alternative cross-platform packaging systems.

I'd like to use it mainly because I swap between different distros frequently, so it would be very easy for me to use a USB or cloud sync to setup Synapse once again if it were available as an AppImage.
