Add data generator support for required mods

Browse Source 
We've supported resource conditions in the upgrade JSON for an age, but
don't expose it in our data generators at all.

Indeed, using these hooks is a bit of a pain to do in multi-loader
setups, as the JSON is different between the two loaders. We could
generate the JSON for all loaders at once, but it feels nicer to use
the per-loader APIs to add the conditions.

For now, we just support generating a single condition - whether a mod
is loaded not, via the requireMod(...) method.
