Crafting ease-of-use tweaks

[Matthew Cline]

1) An "automatically add fuel as needed" checkbox for crafting stations that use them (camping fire, smelter, etc)

2) Ability to craft combinable-items from the crafting menu by clicking "craft", in addition to using the current combine-items UI.

3) In the combine-items UI, have a "combine all" button that combines as many times as possible, instead of having to spam the "combine" button.

4) In the combine-items UI, automatically add a replacement item if the current item gets used up (specifically, replace an empty bucket with a non-empty water bucket when making dough).
