[scribus] New for 1.6.0

[John Jason Jordan]

Yes, I know it is not ready yet, but I'm still trying to find out what
new features are already confirmed for 1.6.0 and those that are still
hoped for. I can't find this anywhere. I do find an occasional mention
of a specific feature on this list, but nowhere can I find a summary
list. Does it exist? Is there a link to it?
