Swedish translation

Imported Swedish translation to localization server and removed CVS file.

If anyone wonder why the translation is gone, please see Maintainer News dec 7 2010:

A. If you are a translation maintainer: you've already been contacted, and
your team is in the process of moving from drupal.org to localize.drupal.org.

B. If you are a translator: stop working on .po files in CVS (either for
Drupal core or contrib), instead import existing .po files from CVS to
localize.drupal.org (if not already), remove the imported file from CVS and
work on localize.drupal.org from now on.

C. If you are a drupal.org project maintainer: do not accept .po files
anymore in your issue queues and remove your .pot files from CVS; tell people
to use localize.drupal.org.
