[development] Updated closed issues

[Fernando Silva]

Hi,

I want to ask Drupal.org maintainers to update closed bugs (closed,
duplicate, wont fix, etc) which have version "x.y.z" to another
version. Ideally, it should be moved according to the issue last
update, but to simplify things it can just be updated to 6.x-dev.

Thanks,
  Fernando

PS: "x.y.z" issues has only 6 pages, meaning that it can be removed
very soon from the version option list.
