ox-ravel.org: simplify `org-ravel-define-exporter'

ox-ravel.org: (org-ravel-define-exporter) instead of macro use
	      `org-ravel-export-to-file' and `org-ravel-export-to-buffer'.

ox-ravel.org: (org-ravel-export-to-file) handles file naming when FILE
	      arg is nil.

ox-ravel.org: (org-ravel-export-to-buffer) handles buffer naming when
	      BUFFER arg is nil.

ox-ravel.org: (org-ravel-export-to-file-or-buffer) macro is deleted.
