Bug#809690: mention where to send bug reports on the man page

[積丹尼 Dan Jacobson]

Package: proj-bin
Version: 4.9.2-1
Severity: wishlist
File: /usr/share/man/man1/proj.1.gz

The Debian proj, cs2cs man pages should have a BUGS section saying that
there is indeed a place to report bugs upstream again.

That way working offline one wouldn't queue them to bugs.debian.org.

Also

"       http://www.remotesensing.org/proj

                              2000/03/21 Rel. 4.4                      PROJ(1)"

is at the head of a long redirect chain that might break any day, and
should be revised...
