Bug#4125: libpaper should ask for papersize

[Erick Branderhorst]

Package: libpaper
Version: 0.4-1

Right now libpaper comes with a /etc/papersize file containing "letter  "
at the first line.  IMO it should ask at postinst time what papersize is
wanted and should create /etc/papersize with the received value.
