   per-upstream defaults

Changes:
2.19
----
 - Disable high-DPI scaling on Windows
 - Links makes it possible to specify scaling of text and images in the
   dialog windows, so this should preferably be used instead of
   system-level scaling
 - Fixed a crash on invalid IDN URL, such as http://test,ï.com/
   (found by lsxvdqe@gmail.com)
 - Make it possible to select other fonts, using fontconfig and freetype
 - Show certificate authority in the "Document info" box
 - Use international error messages
 - The -dump switch didn't report an error if write to stdout failed
