Cooked meat stack size increase to 50

[Elrood 54]

Right now cooked meat stack at 30. Full stack will decay in ledger in 20 hours. 
Exactly the same as raw meat. 

This means on PvE its nearly useless and without excess resources there is no point in making it. 
Its faster to eat raw meat and to get full stomach, small lose of health (half health without any points in hp) means we can walk it out easily. 

If we could increase size of the stack to 50 (or 60) we would actually get tangible benefits from cooking meat:

1. It would take less inv space than raw meat

2. it could actually take longer than 24 hours for stack to decay, so if I logged out with full stacks in ledger, next day i would have a bunch left when i log in.
