cmd_pm2offliners.lua - no minlevel or oplevel

[Sopor]

When cmd_pm2offliners.lua was removed from cfg.tbl it is no longer possible to set any restrictions.

    cmd_pm2offliners_minlevel = 60,  -- min level to use this command? (integer)
    cmd_pm2offliners_oplevel = 100,  -- min level to delete the message database? (integer)
    cmd_pm2offliners_delay = 7,  -- how many seconds after login before send? (integer)
    cmd_pm2offliners_advanced_rc = false,  -- warning: this feature adds a complete list of all regusers to the rightclick, this could brings problems in bigger (60+) hubs!
