org-contacts: Use progress-reporter for cache update message

* contrib/lisp/org-contacts.el (org-contacts-db): Use
`make-progress-reporter' instead of `message' for messages. Also
change the sentence to present progressive tense.
org-contacts: Fix org-contacts-gnus-article-from-goto

* contrib/lisp/org-contacts.el (org-contacts-filter): Add a PROP-MATCH
argument.
(org-contacts-gnus-article-from-get-marker): Search for email as a
property not a tag.

`org-contacts-gnus-article-from-get-marker' seems to assume that the
contact properties exist within the contact's tags as colon-separated
KEY={VALUE} entries.  This isn't the case for me, using org-mode from
git master.

This commit adds a PROP-MATCH argument to `org-contacts-filter' so
that `org-contacts-gnus-article-from-get-marker` can filter by the
EMAIL property.

ox-koma-letter.el: No default opening and closing line.

	* ox-koma-letter.el (org-koma-letter-opening): No default / set to nil.
	(org-koma-letter-closing): No default / set to nil.

	We should not assume a formal English opening and closing
	line.  A letter requires many personal options, such as the
	address, so it is no more work to also these options.
