Coinage is a special case, as there is no penalty for switching from coinage to something else: might it make sense for the AI to check building want every turn while building coinage (perhaps by having Coinage "finish" each turn)?

So far this is based solely on reading the code.

- Want for buildings is recalculated only once in every 5 turns, or when ever existing production is finished, or becomes unavailable.
- Want for buildings is 0 if some of their requirement is missing.
- Building coinage does not finish, and generally seems not to cause recalculation of the wants
- Building coinage causes reselecting of the build target every turn, but it's based on existing wants

To sum: If AI has no tech for some building at turn 0, it will get want 0, and AI may end up building coinage. If building then becomes available via researching the missing tech, want for it is not recalculated but remains 0. When selecting new target, coinage still has higher want than building with want 0.

At the moment I think the fix to be keeping real want even for those buildings that cannot be built at the moment. Selecting the build target will anyway consider available targets only.
