fix(server/commands): giving keys

* fix: resolve error when giving keys without id

When attempting to give keys to another player without an ID an error was given.

It had to do with closestDistance being nil.

* feat: Added new config setting

Added a new config option "distanceToHandKeys = 3" so players can adjust the range at which to hand keys over.
