New hooks :
Added a new hooks :

• afterInitialize called after chocolat is initialized
• afterImageLoad called each time an image is loaded (see #47)

$('#example').Chocolat({
    afterInitialize : function () {
        // your code here
    },
    afterImageLoad : function () {
        // your code here
    }
});

Fixed missing var declarations :
Missing var declarations made minifying and concatenating failing on some setups.
