Lowercase crates

Created by: Kammerjunk

Turns all the crates lowercase. Difference between this and this RnD crates become research and development crates. I've left some of the stacks of packs with capitalised names and made them improper because they look like they're supposed to be names, not just words (for instance, I've made the "medical stack of packs" lowercase but made the "Tools n Engineering stack of packs" improper). Not sure if it's the intended effect but it's not like it's hard to change.
