Bug#655999: [bugs.debian.org] Reporting documentation - "What package does your bug report belong to?" points to user support groups

Package: bugs.debian.org
Severity: normal

The ITS requires a package to be specified to send a report. If the reporter doesn't know which package is concerned, our documentation about bug reporting says:

If you are unable to determine which package your bug report should be filed against, please send e-mail to the Debian user mailing list <mailto:debian-user@xxxxxxxxxxxxxxxx> asking for advice.
http://www.debian.org/Bugs/Reporting

debian-user's topic is user support.

For technical discussions about development, the default group is debian-devel@xxxxxxxxxxxxxxxxx
Reference: http://anonscm.debian.org/viewvc/webwml/webwml/english/Bugs/Reporting.wml?r1=1.18&r2=1.19

While we're at it, we shouldn't require reporters to indicate a package. If the ITS technically needs a package to be indicated, we could tell reporters to indicate a pseudo-package when they don't know, perhaps "unknown" or "default".
