Support a new file format that allows people to share their UTM config without having to share disk images and other personal data. Maybe even maintain a database of "common" configs (Windows XP, Android, MacOS, etc) to aid in VM creation.

Improvements to .utm in v2.0 allows for templates and existing VMs to share a format.
