- oer+MySQL will now only fallback to making USERHOST
  queries, a WHO query is done on channel join
- made some code cleanup relating to processenv()
- oer+MySQL 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
- nstats was broken for join count if new logging (global
  flag "n") introduced in -26 was set, fixed
- "add flags" and "del flags" were doing exactly the same
  thing as "edit flags", fixed
- 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 -19, the bug would cause
  unbans etc. not to be scheduled, fixed (Thanks Renzo,
  Emperor| and Azo)
- list floodvars listed nickflood expire twice, fixed
