(svn r9613) -Feature: Make it possible to have some control over the town growth. The

default rate is TTD's original rate, and to approximate OpenTTD's previous
behaviour the rate should be set to "Fast" or "Very Fast". Town growth can be
switched off entirely, and if so, buildings will not be rebuilt. It is also
possible to specify a proportion of towns that grow twice as fast as the
others.
