[x3d-public] value_changed event if value does not change

[Andreas Plesch]

Any takers for below ?

To sharpen the question a bit: Would any (known) scene break if
interpolators would not generate a value_changed event if the key values
stayed the same ? As in the central intervals of keyValue='0 1 1 1 1 0' ?
