+5 and +10 to Bills

[Silvador]

I'd really like to have the option to, when opening the Details window on a crafting Bill, add groups of 5 and 10 at once. Currently we can only add 1 or 25 and when we only want to add something like 15, it's still very tedious to sit there constantly clicking that +1 button.
