Update to changes in 'splib' and 'sptrans'

Fix missing date in ChangeLog

Fix bug where game crashed when asking the "ritual question"

Correct fnYESORNO so it is a FUNCTION not a SUBroutine.

Fix bug in calculation of number of farmers

If all the population were assigned as workers then the number of
farmers would be the same as the previous season, instead of 0. This
could in turn lead to a negative number of soldiers being calculated.

Update version number to 1.0.1
