cookbook: Added a second example to show "overlapping" transitions

Browse Source 
Added another JSON example to show how transitions can
be easily overlapped when using ClutterAnimator (two
sequences of 5 transitions, simultaneous with two
sequences of 1 transition).

Modified the C JSON loader program so it can be used with
this example as well.
