Supply shuttle and crate fixes

- Supply point generation no longer increases over time, leading to a total of around 45000 points generating after 150 minutes
- Supply packs can have access set as either a number or a list; either is transferred to crates' req_access var correctly
- Non-secure reagent cartridge crates no longer use secure crates
- Closet/crate examine now calls ..() in all circumstances, not just when the user is more than one tile away
- Possibly more I can't remember
