[x3d-public] start timer at fraction 0 after scene loading

[Andreas Plesch]

Another method apart from a ProximitySensor to start a timer without
user interaction after scene loading is to use two TimeSensors. The
first has loop=true and its only purpose is to trigger the second by
routing its cycleTime to the startTime of the second TimeSensor. The
first also stops itself by routing its cycleTime to its own stopTime.

Here is an example modified from the cycleTime NIST example:
