Bug#573997: epiphany-browser: Headers and footers not printed, margins not respected

[Apelete Seketeli]

Just realised my printed test case didn't have any header or footer
either, even though I set them in gconf too.
The margins are printed fine though, so my guess is header and footer
support isn't available in Epiphany yet, and that may be why there isn't
a config option for that in Epiphany at the moment.
