Topic: New buildings for the period before mainline railways

[wlindley]

Per this pull request, a Large Inn (passengers only, capacity 120, build cost 600¢, maintenance 8¢) to complement the Staging Inn.  (With icon and snow images. One rotation only for this square building.)

Thank you very much for this: however, I think that we are missing the icon file from the commit, as this will not compile.
