- Fixed a longstanding bug where oer would take user@host
  from the server as it's hostname instead of just the host
- oer will now also use the user id returned by the server
  instead of using the one in the config
- Added a bantype setting for channels, see online help
- Added a "all" and a "user@host" type to adverts
- vhost flag wasn't set on edit vhost, fixed
- Changed some memory allocations and de-allocations from
  static to dynamic. The change should save up some memory
  (the more users your bot has, the more memory is saved
  by these changes)
- Did some code cleanup
- oer incorrectly tried joining a channel waiting
  OER_AUTO_REJOIN_TIME seconds in between joins (the
  correct one is OER_DELAY_BETWEEN_REJOINS
- Added --enable-profile to configure (enable this to get
  profiling information which you can study with prof/gprof)
- Decreased the default net join period from 30 to 15 seconds
- last & seen will now accept a second argument specifying
  how many entries to list (1..MAX)
