do-release: Make artifacts public automatically

This makes it more likely that new artifacts and images might be
publically available before they are officially announced, but I can't
see that causing problems.

Changes were required so that the script will only make public the files
that are part of the release, and not do 'mv *' from a configured
location into a publically shared location while unsupervised. The
intermediate .tar file is now removed from the artifact server when the
script completes.

The script no longer outputs debug messages by default, because the
really long SSH commandlines used to move files into place make this
pretty hard to follow. Some extra status() calls have been added
instead.

There are a few other cosmetic changes in this commit.
