- Fixed a potential crash when changing nicks, this bug was
  introduced in -48 (Thanks Renzo)
- Updated BUGREPORTING
- There was a lurking bug in the message parsing, fixed (oer
  would obey to commands even if there wasn't a whitespace
  delimiting the prefix or nick name of oer and the command)
- add/del/edit chanflags was missing a channel sync, fixed
- Improved security for "list adverts" (when sent to a
  channel, oer will check that there are no users that
  shouldn't see the advert, if there are the advert won't
  be shown)
- Added chanflag "c" to disallow ACTIONS on channel
