2.15.41 Regtests

[Phil Holmes]

I've been doing a bit of work with my pixel comparator, and now have a 
mechanism to generate a web page from commented results.  Running the 
checker on 15.41 versus 15.40 gives about 100 changed files, most of which 
are subtle changes, some of which come from a changed forte mark.  I've got 
a web page with what I believe are significant changes.  Its address is:

http://www.philholmes.net/lilypond/regtestresults/

Please look at it and see if these are intended changes.
