SMuFL name mapping update

[Owen Lamb]

Hi all,

It's been a while, and I apologize. Evidently I'm not as good at 
managing my own schedule as I thought I'd be.

That said, I'd like to pick up where I left off, choosing once and for 
all what LilyPond glyphnames (i.e. clefs.G) go with what SMuFL 
glyphnames (i.e. gClef), so that, in the future, Emmentaler can become 
properly SMuFL-compatible.

Instead of an Excel sheet, I've prepared a somewhat janky GitHub Pages 
site here: https://wolfgangsta.github.io/emmentaler-bravura/. It 
includes my current opinions on what glyphs should match up where, and 
indicates possibly contentious decisions.

But most importantly, it displays the glyphs themselves, so anyone can 
compare Lily's and SMuFL's de facto standard fonts at a glance, and at 
the same scale. (I caught a couple of my own errors myself while working 
on it!)

I've put in the same four glyph sections I presented last time, with 
many opinions revised. As I have time, I'll add the next few, et cetera, 
until all 25 sections found in the LilyPond manual are accounted for.

So, please--if you're interested, if you'd rather not let some mistake 
of mine make its way into our font--give it a look and tell me what you 
think (even if you think it's all good).

Sincerely,
Owen Lamb

P.S. I'd particularly appreciate the help of anyone who's had experience 
with Stockhausen accidentals. But really--anyone and everyone should 
give it a look! The more pairs of eyes, the better.
