add tests/testexpand.c used to test the expand props on GtkWidget

There are two colored boxes with toggle buttons nested
inside several GtkBox. Toggling these to expand mode
should automatically propagate expansion up through
the several GtkBox such that resizing the window
results in resizing the colored boxes.
