Craft ruleset now has 8 more fields:
`maxSmallSoldiers` = maximum allowed number of 1x1 soldiers, default -1 (unlimited)
`maxLargeSoldiers` = maximum allowed number of 2x2 soldiers, default -1 (unlimited)
`maxSmallVehicles` = maximum allowed number of 1x1 vehicles, default -1 (unlimited)
`maxLargeVehicles` = maximum allowed number of 2x2 vehicles, default -1 (unlimited)
`maxSmallUnits` = maximum allowed number of 1x1 soldiers and 1x1 vehicles, default -1 (unlimited)
`maxLargeUnits` = maximum allowed number of 2x2 soldiers and 2x2 vehicles, default -1 (unlimited)
`maxSoldiers` = maximum allowed number of 1x1 soldiers and 2x2 soldiers, default -1 (unlimited)
`maxVehicles` = maximum allowed number of 1x1 vehicles and 2x2 vehicles, default -1 (unlimited)
Of course there are still the two existing fields:
`soldiers` = total of all imaginable units, default 0
`vehicles` = all units minus 1x1 soldiers (i.e. 1x1 vehicles, 2x2 vehicles and 2x2 soldiers), default 0
