Gix has a schema migration feature

[Zulko]

Motivation

If Gix introduces a breaking schema change, this will break all the existing Gix projects out there. We need a way to ensure the schemas auto-update.

Specs

• gix-renderer has a new function that will convert any project data to the latest version.
• Any project loaded to the editor undergoes this migration to the latest schema automatically.

Technical details

• Here is a good schema migration pattern explained.
