Ported from cosmonarchy-bw-release fe42f19. The .tbl.txt sources were
regenerated from this repo's own .tbl binaries rather than copied, so
images.tbl.txt and unitnames.tbl.txt carry the prerelease strings
(Askosi Sons of Ash, Faction Selection Askosi, Terran Fleshthief,
Forerunner Lumen) instead of the release ones.
tools/tbl is committed as real files here; in the release repo it is a
bare gitlink with no .gitmodules, so it comes out empty on clone.
