This patch changes rule that city center always has road to that city center roads are subject to terrain restrictions. If terrain cannot have road, city center will have no road. If city is on river tile and player doesn't know bridge building, city center will not gain road (but existing one is not removed if city is conquered by player who lacks required technology)

Testing has been minimal so far. I would be quite surprised if there will be no iterations of this patch before committing. I set status to "Ready For Test" instead of "In Progress" regardless, to keep tthe option that I'll commit this one if it passes my tests.

This patch may seem like something that changes one arguably wrong rule to another one that others may consider wrong, and does so by making code more complex and bugprone. I should mention that having existence of roads to always respect terrain restrictions makes some future patches much more simpler, cleaner, and less bugprone.

Cities on river tiles not having roads in the beginning of the game can make huge difference. That needs a lot of testing, and possibly some other changes to balance it, or even just new, more compatible with future patches, implementation of the feature that cities on river tiles get road even when bridge building is not known.

While testing this patch I noticed that roads in cities were not upgraded when I granted technologies from editor. That may be bug in existing code (=stable branches) meaning city center roads are not upgradet when one gives Railroad-technology in editor. This should be checked, and separate bug ticket opened for it if it indeed is buggy.
