SWAT translations: complete them and add some more?

[Christian Perrier]

I just went on a Debian bug which was requesting to add a Finnish
translation for SWAT (the translation was added already, indeed).

That made me discover the source/po directory with translatable
strings from SWAT.

Several of these seem outdated/incomplete and probably many more
languages could be added.

Would you people mind if I attempt to use the power of the Debian i18n
community (i18n/l10n is another hat I have in Debian) to complete these
and, very probably, add some more translations (probably a lot,
indeed)?

My only conern is the files being named foo.msg instead of the quite
standard foo.po but that is not a big deal. Having a complete and
up-to-date POT file provided with the source code tarball would help,
also.
