## Description:
Adds an optional `additionalNations` array to map manifests (info.json /
manifest.json), used as a name pool when a game requests more nations
than the map defines (HvN, private lobbies, solo games).
Suggested by mapmaker PatrickPlaysBadly.
When the requested nation count exceeds `nations.length`:
1. The deficit is filled by random picks from `additionalNations`
(collisions with manifest names are skipped).
2. If `additionalNations` still does not cover the deficit, the
remainder is generated procedurally as before.
Each entry supports `name`, optional `flag` and optional `coordinates`.
If `coordinates` are provided, the picked nation gets a spawn cell
(otherwise it spawns like the procedurally generated ones, with no fixed
location).
`Nation.flag` is also relaxed to optional, since many existing manifest
entries already omit it.
