- oer will now only fallback to making USERHOST
  queries, a WHO query is done on channel join
- made some code cleanup relating to processenv()
- oer will now write a signoff message in case it detects
  a stoned server (if you see a "stoned server" signoff
  message, it probably means that the ping frequency in the
  server setting is too small, you need to increase it)
- Fixed chanflag "U" for last, seen, quote, and nstats
- Added global flag "p" to tell oer not to check for
  a stoned server (some networks seem to have disabled the
  defacto standard PING-PONG feature)
- Fixed several issues with chanmode, chankey and
  chanlimit (Thanks Renzo)
- There was a very hard to find bug in multiple mode
  processing that was introduced in -41, the bug would cause
  unbans etc. not to be scheduled, fixed (Thanks Renzo,
  Emperor| and Azo)
