* src/statusline.cc (CounterBox::CounterBox): Change the shadow
type to Gtk::SHADOW_ETCHED_IN.  Still looks somewhat ugly though;
I need to think of something better.  Also enable the single line
mode property of the numeric labels, in order to avoid resizing if
the digits in the font have different height.
(StatusLine::StatusLine): Increase HBox spacing to 3 pixels.
