Address review on the role api

- Roles are objects and everything done to or with a role is a method on it:
  assign, unassign, has_player, has_permission, is_higher_than,
  is_lower_than, get_players, get_player_names, print. Assignment has one
  entry point, role:assign(player, options), with local_only as an option
  rather than a second function.
- Roles are looked up by clusterio id with get_role; get_role_by_name searches
  the list for the few places, such as configs, which only know a name. The
  name map and the ordered list are gone, get_roles sorts on demand and the
  index field is replaced by the comparison methods.
- Players are LuaPlayer objects only, with nil or index 0 for the server.
- get_higher_roles and get_lower_roles replace print_to_roles_higher and
  print_to_roles_lower, call sites loop over them with role:print.
- Permission groups are removed from roles again, exp_groups owns the mapping
  from roles to groups.
- Seeding is a SeedRolesRequest behind a button on the roles page rather than
  running on first start, and creates only the roles; the player assignments
  are dropped. The seed lists each permission once at the lowest role which
  has it and lets the parent chain carry it up.
- System commands unlock for core.admin rather than a permission of their own.
- Role metatables are registered with Storage.register_metatable so the
  methods survive save and load, which the role records in storage needed.
- The player list auth uses Roles.player_outranks directly, and the event
  carries role ids rather than names.
