Subject: [PATCH] configure: Add --with-id3tag-headers/libs.

If libid3tag was intalled at a non-standard location, the configure
script would not find it. Currently there is no way to tell configure
to look for libid3tag elsewhere.

This adds two new options, --with-id3tag-headers and --with-id3tag-libs,
to overcome this shortcoming.
