Changes:
Overall better font readability
Maps are tagged by difficulty.
Save Map UI now lets you choose an icon and a difficulty tag.
Renamed "Promote Moderator" menu to "Player Permissions".
Fixed a bug where promoting a player to moderator would kick them from the server.
Fixed a bug where promotion menu didn't update immediately.
Added finer granularity to player permissions by adding 'editor' role where the player can edit the map but not kick other players.
