Subject: [PATCH] Extract Travis before install script steps into a separate
 file

This allows to do make these steps more complicated, e.g. avoid using apt-get
under non-Linux (and even non-Debian/Ubuntu) platforms.

Also install GTK+ development package explicitly, while it's already available
on the older Travis Ubuntu 12.04 VMs, this is not the case for the newer 14.04
ones.
