Version 1.6.0

Version 1.6.0 enables 'overlapping transitions', i.e. allows embers with 'uncertainty ranges' which span across each other (e.g. risk can be assessed as potentially above or below 'high' at the same time for a given hazard level). Technical changes enable files to be opened in recent versions of Adobe Illustrator and removes a bug (crash) which may have occurred in specific cases when the user selected 'CMYK' from the 'Graph production' page.
