feat(3p/lisp/mime4cl): search for first (default) mime text part r/2853
Adds a simple generic function find-mime-text-part which returns the first suitable text/* part in any MIME part it is given. Has no meaningful alternatives handling at the moment: It will pick the first text part and doesn't allow specifying a preference.
