Subject: [PATCH] ox-koma-letter.el: Add support for url variable

* contrib/lisp/ox-koma-letter.el (org-koma-letter-url, org-koma-letter-use-url, org-koma-letter--build-settings): Add support for url variable

Copied phone-number variable code, pasted it and changed references from phone-number to url.

Tested "url" with "#+URL: url", and "use-url" using "#+OPTIONS url:[nil|t]".
