Production Calculator Changelog

Decided that it was actually a bad idea to ignore the quantity of every item except the first one. Thanks to Michelle S. for pointing this out.
Took yet another stab at weapon costs. They should be in line with what NERO New Brunswick are using now. Still don't know if its right, the only thing I know about weaponsmithing is that the rules are very badly written. Base weapon costs should be right... silver costs are arbitrary anyway, SR costs should be right, and fates help us all if you want to combine silver and SR.

Fixed Shatter Resist cost again, since last time Andrew and I had a misunderstanding.

Fixed Shatter Resist cost - Now its 80 no matter how many SR's you put on (as the cost actually is supposed to be). Blame me misreading the rulebook for getting this wrong, and a big thanks to Andrew I. for pointing out the correct way to do it.
Fixed Silvering Costs - they were actually 10x too low. Silly me forgot that I was working with silver and not copper.
Changed some values to use longer integers, so it should be harder to overflow now.

Fixed Arrow Costs - they now comply with the 8th edition errata as of today. (Also, arrows are now changed to buy in Quivers (20) rather then lots of 4)

Added Armour Production
Added Weapon Production
Added Silver and Shatter Resist attributes
Added event length, so that you can calculate total production based on more then one day. (aka: the results actually make sense in real world use now)
Printing actually works now
Changed production cost from levels to points in item list
Level restrictions are more closely checked.
All kinds of internal changes to make some stuff work better

Initial Release
Can only calculate production for scrolls and potions.
Can enable or disable workshops.
Skill level restrictions are only partially enforced. (main problem is that you can make more items then your level would allow, but it does correctly block you from making items which are beyond your ability entirely).
