[GNUe-dev] Highlight color for widgets

[kilo]

Hi,

my recent patch to GTK2 UI driver depends on a config setting in
gnue.conf. I've also patched the sample.gnue.conf in gnue-common/etc,
please review that for changes needed in your own gnue.conf for
highlighting to work.
In case you don't put the required lines to your gnue.conf, you won't
get highlight on focused widgets.
See commit #6638 for further details.

Thanks
