CHANGE: Reduce the default rolling resistance for roads in line with research
ADD: The max_intransit_percentage is now scaled to the ratio of the time that it takes a factory to consume its stock to the lead time for deliveries of new stock. This means that a "max_intransit_percentage" of much lower values (a little higher than 100% is recommended) can now be specified safely.
CHANGE: Adjust simuconf.tab to take advantage of the previously committed feature
CHANGE: Skip calculation of adjusted maximum_intransit_percentage when the base value is zero
FIX: Occasional crash on saving
VERSION: Step to release build
FIX: Compile error in GCC
VERSION: Increment to 11.17
FIX: Clear the max_intransit_percentages hashtables before recalculating them.

Fixed: waiting list of halt gui
Changed: another optimization: no need to get the factory name explicitly as it is gotten in gb->get_description() as well.
