Title: my little aproach to create new Pencil File Format - zipped one file, this method uses QUAZIP library

Unlucky there is a bug - after opening one file and making changes you cannot save your job neither to old file nor to new one - Pencil crashes during saving file - on my linux this bug exists also on a clean chchwy:master branch (without my changes)
