Allow updates with AppImageUpdate and AppImageLauncher

[Lvaskz]

Hello, I usually realize that there are new Cpod updates. That is very convenient, the problem is that there is no way to update the cpod, so you have to download the new version and discard the previous one. However, if you make it possible to update cpod with appimageupdate and appimagelauncher it would be easier. Of course, it would also be necessary that cpod can make notifications of new versions and perform the update from appimagelauncher.

Hi,

Currently CPod has an electron-updater-based update system which automatically checks for updates when the application is started and notifies the user accordingly. There is also an option to allow pre-releases when checking for updates (I haven't released a "stable" CPod since 1.11.0). The update will then be installed if the user agrees.

Electron, the framework that CPod is built on, doesn't seem to support AppImageUpdate integration. So this doesn't seem like something I'll be working on implementing in the near future.
