[PATCH] Better senddoc mailto selection for null and default mailer cases

senddoc.sh has separate cases for unknown mailer and for no mailer
configured. Both of these cases attempt to find a desktop "mailto"
handler, using different methods. This patch merges these two cases
and the strategies for finding the handler.

Note that there is ambiguity as to the proper mailto keyword for
attachments. I've used 'attachment', per direction in the referenced
xdg list email.

This builds on https://bugs.freedesktop.org/show_bug.cgi?id=32621
