Show Items first when clicking on a crate/Stockpile

The title pretty much says it all, I just thought it would be neat to see all the items that are in a crate first, that way its easier to go through crates and find Items. :smile: Another option would be to open the category menu when you place a crate for the first time but otherwise open the item menu, that might be too much unnessecary work for the Devs though :grin:
