Add appimageupdatetool support / remove zsync (#1394)

NOTE, only the command is added. If the AppImage supports delta updates, appimageupdatetool will be used as default... otherwise version comparison will be used.

This change is also to incentivize users to push upstream developers to implement delta updates.

Also removed zsync references to standardize this group of scripts.

This commit also solves an issue on updating some apps with a broken AM-updater script.
