Use "Next Generation AppImage" instead of "Type3"

Change of wording, at the request of the creator of AppImage @probonopd

This is a continuation of what has already been changed in "files.am", see 368f2fa

Technically, these are Type 0, as you can see from the AppImageSpec:

Reserved for not fully standards-compliant AppImages (e.g., portable binaries that look and behave like AppImages on a user level, but do not conform to a standard on a programming level).

Also, please be aware that there are many different implementations, so the only reliable source on what can be assumed is AppImageSpec:

• https://github.com/linux-packaging-rs/appimage-type2-runtime-rs
• https://github.com/orivej/static-appimage
• https://github.com/tim-janik/appimage-runtime
• https://github.com/mensinda/libRuntime
• https://github.com/AppImageCrafters/appimage-runtime
• https://github.com/haampie/appimage_runtime
• https://github.com/CalebQ42/appimage-runtime
• and probably more

Technically, these are Type 0, as you can see from the AppImageSpec:

sorry to disappoint you, but if this is "zero", is the best "zero" I have ever seen!

Also better than 1 and 2!

Congratulations :)

PS: I'm still waiting for this PR to be merged AppImage/appimagetool#9

once it is ready, big things will come, for this project and several others... if not for all other projects that choose AppImage.

I trust in your work 👍

As per the AppImageSpec (did you read it?) type 0 just means "everything that is neither type 1 nor type 2".
