changes to the orphaned wiki page.

[Michael J. Knox]

Hi all,

I have made some small changes to the orphaned packages wiki page. It 
now can document retired packages.

With the lack of an official policy on how a package is to be retired, 
it's really up to the packager to make that choice. This is just a means 
to record this status.

Some basic criteria:

No upstream
No activity upstream
Release critical bugs (where there is no upstream to fix)
Packager does not want to be responsible for the above.

There is no policy about taking a package out of retired status, just 
have to be aware that you will take on responsibility for release 
critical bugs.
