Alpha 5 patch 9 hotfix 47

This update introduces resource categories in the statistics window. It will get more precise once Alpha 6 will bring the new unit system, but even now it should help identify supply and demand trends and make some prudent decisions.

Added/changed:

• Some minor optimizations

• Added text flow around image in help pages

• Can now use command line argument like "ostriv.exe -map level01" to start on specific map (mostly for dev purposes, but who knows)

• Added help page for stone mining camp

• Added a few more resource carry models

• Improved construction workers logic (don't go with a gang of 20 to build a single cart parking)

• Added options in cartwright to repair specific vehicles (or none)

• Added category totals in resource stats

Fixed:

• Roads could get weird after loading one save after another

• Imported oxen were female and could give milk

• Wagon sheds and farms could secretly breed animals

• Crash when barber surgeon's patient didn't wait for him and died

• Fallow fields could restore too much nutrients in some cases

• Changing crop could immediately restore field nutrients
