Greetings everybody,

this user-friendly modification has been discussed for a while but
nothing concrete had been done so far.  Therefore I took the liberty of
proposing a very simple patch, since this modification is something I
really really need (well, not me, but rather the French music schools,
students etc. whom I introduce to LilyPond every other day).

Please review this patch on http://codereview.appspot.com/2606042 and
the issue on http://code.google.com/p/lilypond/issues/detail?id=903 --
the discussion has somehow gone South on this page, but I hope that my
patch is basic enough to make things simpler and more straigthforward
:-)

Cheers,
Valentin

Description:
Fix #903: Add shortcuts for note names languages.

This commit adds a new file, lang-init.ly, that
introduces new shortcut commands for notenames
language selection: instead of using \include "italiano.ly",
just use \langItaliano, and so on.

Standalone shortcuts have been defined for all available
languages.  A different syntax has been considered, such as

  \lang "italiano"

However, since the only way to pass arguments is currently
through a music-functions, and since you can't have toplevel
LilyPond definitions inside a music function, this would
require to modify either the parser (a rather heavy change)
either the italiano.ly&co files, which would break compatibility
with existing code.  The way I chose was the lightest, safest
and the most straightforward.

Full compatibility with the old syntax is preserved.  Once people
get used to the new syntax, we may consider a slightly different
implementation (or not).
