Corrects links to manuals in many languages

A number of the links on the Development pages for the various languages point to pages that don't exist (e.g. the Czech page http://lilypond.org/development.cs.html) or don't point to translated pages when they do exist (e.g. http://lilypond.org/development.it.html).  This patch _should_ fix many of these.  It's difficult to test properly, since it relies on interactions between make doc in GUB and make website on the server.  However, I believe it's a step forward and would like to get it into master fairly quickly.

Since news-front.itexi is included in web.itexi, I suspect that deleting this
file would cause the entire build to break.  Did you mean to edit hu/web.texi as
well?

I would rather leave this file alone, or possibly add a "news" item saying "this
translation is out of date".

Well...  If news-front isn't in the translation, it's found in the en build 
and used.  Most of the translations work like this.  Except it does cause a 
make website to break, because of the links file which is previously 
created.  Can't remember the exact name.  Locally, I fixed this by nuking 
build and rebuilding from scratch, and all was well.  As it turned out, the 
website build on the server failed for the same reason, so I resorted to 
renaming the build directory on the server and it rebuilt from scratch, so 
all appears OK.

It was a very out of date file and not used anywhere in the build.

Thanks for the comments.  Appreciated.

BTW - my recent patches have corrected a _lot_ of broken and missing links. 
Prior to this, all of the links on http://lilypond.org/glossary.hu.html were 
broken.  This was true for most of the .hu and .cs docs.  They now all go to 
a page that exists.
