Subject: [PATCH] POGeneratorSettings: add a property to change the max line
 length default value

In Weblate, the maxlinelength is set to 77. If we want to use this package to touch PO files managed by Weblate, it kept being updated by weblate again, then updated by Karambolo because they don't use the same line length
