Fixed bad committish and es.po in spanish web site

[Daniel Tonda]

I changed the committish ids for files showing a bad committish when doing:

make LANG=es check-translation

> I've also removed the dirty page
> es/about/automated-engraving/applications.html

So whatever is done to this page is of no consequence from now on?

> Before translating the tutorial, LilyPond's es.po should be revised too.

I did some revising of es.po also, are there any special
considerations for es.po?

I attach the diffs, for the bad committish and es.po.
