Remove extra file references from docs.

gntversion.h only exists on default, not release-2.x.y, and the other
API indices are not needed since nothing was added in those versions.
#include "gntutils.h"
int main()
{
GntWidget *win, *button;
gnt_init();
gnt_util_parse_widgets("<vwindow id='0' fill='0' align='2'><label>This is a test.</label><button id='1'>OK</button></vwindow>", 2, &win, &button);
g_signal_connect_swapped(G_OBJECT(button), "activate", G_CALLBACK(gnt_widget_destroy), win);
gnt_widget_show(win);

gnt_quit();
return 0;
