[uf-new] [hAudio] fn _or_ album

[Ben Ward]

Regarding the ‘fn and/or album’ pattern in hAudio. I'm not convinced  
this is a good pattern, and it behaves differently to the existing  
pattern in hCard.

Currently, you can produce hAudio with an 'fn', or with an 'album' or  
with both. However, when compared to hCard — say the 'fn' and 'org'  
fields, where organisation name is often also the fn — hCard takes a  
more verbose, and in my opinion more consistent and understandable  
pattern.

So in hAudio:

<div class="haudio">
<span class="fn">Bodysnatchers</span>
</div>

<div class="haudio">
<span class="album">In Rainbows</span>
</div>

in hCard:

<div class="vcard">
<span class="fn">Thom Yorke</span>
</div>

<div class="vcard">
<span class="fn org">Radiohead</span>
</div>

In both hAudio and hCard there is always a formatted name. hCard sets  
a more verbose and easier to follow precedent of always including  
‘fn’ — not optimising ‘fn’ from ‘org’ or anything more complex.

I think hAudio would be clearer to adopt the same pattern, so the  
second (album) snippet would become:

<div class="haudio">
<span class="fn album">In Rainbows</span>
</div>
