Add a preset setting to set max carriable quantity for each consumable

[Dinopony]

Inside preset settings, add a dictionary with:

• item name as key
• max carriable quantity as value

Value needs to be clamped according to what the game is capable of handling / displaying.
Items that are absent from this dictionary keep their original max quantity.

Added functional core in 4188085, but didn't add the preset setting yet to expose it since quantities aren't displayed in the inventory for any other item than Herbs.
Changing this is going to be complex, since all inventory stuff looks heavily hardcoded.
