make list items with quantities

[kommandantredundant]

When packing, often I start while not having items in the desired quantities ready. For example, I need 10 shirts, I put out 7, but I still need to wash 3 more. I cannot check the '10 Shirts' entry on my packing list.
When creating an entry, I'd love to be able to choose between a simple checkbox and a counter, enabling me to set quantities of items, so that I can later tap in the amount of the item done and see how much is missing.

Thanks @kommandantredundant! Coming in the next big release: items with a quantity get a small counter (for example 3/10) in the packing list, and the item ticks itself off once everything is packed.
