Complete rewrite

• Changes storage to SQLite or MySQL - which should fix #2 's issue of social spy settings not persisting
• There is now an option in the config named console-has-social-spy: true which allows console to have the same formatted readout that people with socialspy do
• Options for messaging hidden-players (vanished) and console, as well as config options for what to use as the name for console.
• Formatting for how names appear in direct messages and social spy are in the config, other messages can be updated in the Locale
• The server can now message itself, if you wanted to do that for some reason
• Adds 4 commands
  • /block <user> [reason]
  • /unblock <user>
  • /blocklist
  • /msgtoggle
