Fixing #487. I know use "apt-cache policy", instead of apt-cache showpkg, because it clearly shows which version will be installed. This is basically impossible to test well, so I just added a test that verifies we always get a value back, although I cannot really test that it is the "right" value. Also, I modified the logging of packages so if there is a latest version, you will get the new version number, along with the old, in the log.
