Check for citizens who want to migrate between the cities that overlap. Migrants go to the city with higher score, if the growth of the target city is not blocked due to a missing improvement.
The following setting are used:
'game.server.mgr_turninterval' controls the number of turns between migration checks for one city (counted from the founding). If this setting is zero, or it is the first turn (T1), migration does no occur.
'game.server.mgr_distance' is the maximal distance for migration.
'game.server.mgr_nationchance' gives the chance for migration within one nation.
'game.server.mgr_worldchance' gives the chance for migration between all nations.
Returns TRUE iff there has been INTERNATIONAL migration.

Build city units. Several units can be built in one turn if the effect City_Build_Slots is used (on certain conditions). If the unit consumes population, builds it with a dominant nationality of the citizens (that is always foreign if a foreign nation equals in number of consumed citizens to city owner). Otherwise, the unit will be native. Returns FALSE when the city is removed, TRUE otherwise.

Helper function to create one unit in a city. Doesn't make any announcements. This might destroy the city due to scripts (but not otherwise; in particular, pop_cost is the caller's problem).

Helper function to calculate a "score" of a city. The score is used to get an estimate of the "migration desirability" of the city. The higher the score the more likely citizens will migrate to it.
The score depends on the city size, the feeling of its citizens, the cost of all buildings in the city, and the surplus of trade, luxury and science.
formula: score = ([city size] + feeling) * factors
feeling of the citizens feeling = 1.00 * happy citizens
factors the build costs of all buildings f = (1 + (1 - exp(-[build shield cost]/1000))/5) the trade of the city f = (1 + (1 - exp(-[city surplus trade]/100))/5) the luxury within the city f = (1 + (1 - exp(-[city surplus luxury]/100))/5) the science within the city f = (1 + (1 - exp(-[city surplus science]/100))/5)
all factors f have values between 1 and 1.2; the overall factor will be between 1.0 (smaller cities) and 2.0 (bigger cities)
[build shield cost], [city surplus trade], [city surplus luxury] and [city surplus science] must be >= 0!
The food furplus is considered by an additional factor
the food surplus of the city f = (1 + [city surplus food; interval -10..20]/10)
The health factor is defined as:
the health of the city f = (100 - [city illness; tenth of %]/25)
if the city has at least one wonder a factor of 1.25 is added for the capital an additional factor of 1.25 is used the score is also modified by the effect EFT_MIGRATION_PCT
