Bug#1028643: fontconfig: 2.14.1-3 greatly changes font rendering

[Konomi]

Just to add as an XFCE user this change greatly impacted the look of
my desktop. So while this may be fine for GNOME users, people with
other DEs could be affected by the change.

I also didn't quite get the file correct to revert the change in my
previous email so here's the updated version, as far as I know this
should work correctly.

<fontconfig>
    <alias>
        <family>monospace</family>
        <prefer>
            <family>DejaVu Sans Mono</family>
        </prefer>
    </alias>
    <alias>
        <family>sans</family>
        <prefer>
            <family>DejaVu Sans</family>
        </prefer>
    </alias>
    <alias>
        <family>sans-serif</family>
        <prefer>
            <family>DejaVu Sans</family>
        </prefer>
    </alias>
    <alias>
        <family>serif</family>
        <prefer>
            <family>DejaVu Serif</family>
        </prefer>
    </alias>
</fontconfig>
