is used for all version relationship calculation. The "display version" as sourced from
mcmod.info is used for display purposes only and can be literally anything. Note: they fall back
to one another when they're missing, and to "1.0" if both are absent.
Also, changed @Instance. Now, you can inject *other* mods using @Instance as long as you depend
on them as a "before" or "dependency" relationship. Classes containing @Instance will only be
loaded if the Mod the @Instance refers is present. So you don't have to worry about runtime class
resolution.
