2020-11-27  Scott Pakin  <pakin@pakin.org>

	* ChangeLog, README, mf2pt1.mp, mf2pt1.pl, mf2pt1.texi:
	mf2pt1 no longer generates a UniqueID automatically, only when
	instructed to by the user.  This change assists with reproducible
	builds and is consistent with Adobe's declaration that unique font IDs
	are no longer required or even recommended.

	The documentation has been modified to reflect updated URLs for a
	number of external links and to reference the latest copyright year
	(2020) and mf2pt1 version number (2.6).

	Thanks to Werner Lemberg for bringing Lilypond's issues with
	reproducible builds to my attention.
