Update on bugzilla stuff

[Wolfgang Bangerth]

Dan, some messages from the audit trail are missing. For example, Nathan
replied to c++/38, but it didn't get converted.

Besides that, thanks for making this available. It's much simpler to use,
doesn't need cookies and looks nicer :-)

Cheers
  Wolfgang
