New "Export Instance" template: include game assets for offline restore

[Darthagnon]

Role

I play modded MC on older and offline systems, and care a lot about data preservation.

Suggestion

Currently, instances can be exported, but game assets are excluded (textures, sounds, libraries), so they cannot be restored without an internet connection to the Mojang servers. I would like to export ZIP, and choose "Offline Installer", which will include all necessary assets and libraries for that instance to be restored without an internet connection.

Benefit

This way, MC gameplay won't depend on official servers being available and whitelisted at all times.

A new template "Offline Installer" could be added, which includes all the files currently exported, as well as the assets and anything that would normally be downloaded at runtime referenced by this particular instance, located in (UltimMC and PollyMC used as reference):
