Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
audio/kid3*: Switch to the smaller tar.xz distfile from the KDE mirrors.
There is no change in the content between this and the tar.gz distfile from
Sourceforge, so no need to rebuild.
Update WWW which was redirecting.
