feat: Api to display inventory to remote player

[OldManYells]

This PR adds new command /pinv to open and modify a online player inventory directly.

Please review and let me know if this functionality should be placed some other place.

While I think this is a cool feature I don't know if features that are traditionally added by most major server eco/moderation plugins should be getting added to the server jar when it can be done via plugins.

Additionally if this does get added, the command should fall under a /poseidon subcommand, see this PR for context.

This PR atm only exposes through Bukkit what otherwise is only called by server internal code, the actual feature/command would be added in a plugin or as you mentioned in /poseidon. Not sure if you mean something else or you are referring to a previous commit that also added the command.

Yeah I figured the PR was a draft of some kind going off of it's previous title talking about adding it as a command.

@Garsooon how would you like to go about on this?

Up to @RhysB, however when we were talking about it briefly in both forms (api/command) it probably wouldn't be needed since B1.7.3 plugins already can and have accessed inventories using NMS among other things.
