Move the scenario onto exp_roles and remove the legacy role system

Every call site of expcore.roles now uses exp_roles, and the legacy module,
its config, and the glue which refreshed guis on role events are deleted.
Where a file only renamed the require and the permission strings the change is
mechanical; the rest:

- Jail is now "give the Jail role" and unjail "take it away". The role has a
  higher priority than every other so holding it suppresses them, which is
  what stashing and restoring the roles was for.
- The command role authority derives exp_scenario.command.<name> from the
  command name, and the role parsers use player_outranks rather than comparing
  indexes with their own root check.
- The admin and spectator triggers, and the gui refresh on role changes, live
  in exp_scenario/control/roles.lua; the system commands trigger stays with
  the command authority.
- The player list warn button is keyed on create_warning, the permission
  the command behind it already required, and report on create_report. Both
  were keyed on names no role held, so only root ever saw them.
- The warps and tasks configs say exp_roles where they said expcore.roles.
- The role tables the readme and player list read are replaced by
  get_player_names and get_roles.
