* sheets/civil.sheet: removed duplicate "Danish" entries.

	* autogen.sh:
	* configure.in:
	* .cvsignore:
	* sheets/Makefile.am:
	* po/POTFILES.in:
	* Makefile.am: applied the xml-i18n-tools README's instructions.

	* po/(da de fr hu nl nn no sl).po: merged the translations from
	the sheet files into the .po files. I hope I haven't mixed
	languages...
	* sheets/*.sheet (REMOVED):
	* sheets/*.sheet.in (NEW): moved the sheet files sans
	translations into .sheet.in files.

	* sheets/xml-i18n-unicodify: (NEW) included from xml-i18n-tools,
	because we don't yet want to force all translators to work using
	UTF-8 editors. We'll want to do that sometime (sooner rather than
	later).	Okay, I sing a slightly different tune in po/ChangeLog...

	* dia.desktop (REMOVED):
	* dia.desktop.in (NEW): used also the x18t infrastructure for
	this too.

	* xml-i18n-update.in.kg (NEW): This one will stay in CVS until an
	"official" version of x18t with support for .sheet files is
available.
	* xml-i18n-merge.in.kg (NEW): This one will stay in CVS until an
	"official" version of x18t which doesn't corrupt UTF-8 data in XML
	is available.

	** yes, we are now using xml-i18n-tools to manage the sheet
	translations. For the Win32 build, Nemo stores snapshots of
	translated strings next to the CVS snapshots. **

	* sheets/checktrans.py: suddenly, some sheets have lots of
	translations (objects which existed before sheets, mostly).
	Adapted the formatting.

	* po/README (REMOVED): this is obsolete ! It was ignored, anyway.
