Reload on SIGHUP

This patch makes surf reload its pages when it receives a SIGHUP signal.
This makes it easier for shell scripts to trigger surf to reload.

I'm aware of using xdotool to trigger ctrl+r keypresses for reloading
but I wasn't able to get that to work in a general way. [1]

I'm sending this here in case surf maintainers and users would like to
include this in core - if not I will submit it to the wiki.

Regards,
Charles
