[Feature request] pretty-print the node's meta, hide private meta

[VanessaE]

This should be addressed if possible:

The meta should be displayed in some more readable way, maybe just "dumped" similar to the node definition. Might be a good idea to do the same for the meta inventory, (though the node being inspected in that image is not affected).

Also, I think it would be a good idea to prevent the inspector from revealing "private" meta unless the wielder has sufficient privileges, or is the node's owner.

This item shouldn't be available by default, let's address that issue instead?

[VanessaE]

It's good that it is available though -- but perhaps one ought to have "server" privilege for that to show up?

If my latest pull request goes through then only players with the "server" privilege will be able to use the inspector tool. That's already the case for the chat command version. Hopefully this will protect private metadata sufficiently while still letting modders see it for their work.
