Add CLI support for setting access / permissions levels

[oubiwann]

This will be how someone is granted wizard / world-building rights.

Tasks:

• [ ] Make sure the game data functions can be used without the server running
• [ ] Create an lmudtcl LFE script
• [ ] Add permissions command
• [ ] Add set subcommand
• [ ] Add --user flag
• [ ] Add --level flag

I think I'm going to bail on this. A wyzard can be bootstrapped with a file edit, and then that user can set perms in-game.
