Based on a patch by Matthias, add an "active-id" property for
GtkComboBox and add some convenience API for GtkComboBoxText.
Also, add a test case to gtk-demo.
GtkComboBox now sports a construct-only "has-entry" property which
decides if it uses a GtkEntry to allow additional user input. Also
it has a new "entry-text-column" to fetch strings for the entry
from the model.
This patch deprecates the GtkComboBoxEntry and updates the rest of GTK+
to use the new semantics on GtkComboBox instead.
GtkComboBoxEntry will be removed altogether before GTK+ 3, in a
later commit.
