- Fixed bug where "/rehash" would always reset the "MAX", "JFLOODTIME", and "JFLOODCOUNT" values that
  have been changed from within IRC via the "/set" command
- Renamed the following ircd.conf configuration directives to be more descriptive:

  max_clients -> default_max_clients
  join_flood_count -> default_join_flood_count
  join_flood_time -> default_join_flood_time

- Updated related ircd.conf documentation accordingly
