Allow the use of commands near the Shop NPC or make this more clear

Currently, you can't run ANY commands near the shop NPC. I'm not sure if this is technically "intended" (to prevent teleportation exploits with the NPCs) but regardless it's overly restrictive. At times it's confused me when commands don't work, and I would guess it confuses new players. Ideally, just the problematic commands would be blocked. The only caveat (if it's teleportation commands) is making sure you get all of the Essentials/HomeGUI aliases as there's quite a few. The other option is a command whitelist (all commands are blocked except for known harmless ones, /bal, /baltop, /sb and so on) An alternative option would be to add a message in chat saying "Please exit this area to run commands" or similar
