* This procedure calculates the number of emigrating peasants for the given

* 1) They prefer the less crowded areas.
* Example: mountains, 700 peasants (max 1000), 70% inhabited
* plain, 5000 peasants (max 10000), 50% inhabited
* 700*(PEASANTSWANDER_WEIGHT/100)*((70-50)/100) peasants wander
* from mountains to plain.
* Effect : peasents will leave densely populated regions.
* 2) Peasants prefer richer neighbour regions.
* Example: region A, 700 peasants, wealth $10500, $15 per head
* region B, 2500 peasants, wealth $25000, $10 per head
* Some peasants will emigrate from B to A because $15 > $10
* exactly: 2500*(PEASANTSGREED_WEIGHT1/100)*((15-10)/100)
* Not taken in consideration:
* - movement because of monsters.
* - movement because of wars
* - movement because of low loyalty relating to present parties.
