added a callback when showing tooltips to customize contents

[timkock]

Added functionality to allow for an option to provide custom tooltip contents based on item data as such

cal.init({
    tooltip: true,
    onTooltip: function(date, nb) {
        return $filter('currency')(nb || 0, '€ ', 2);
    }
});

This example pertains to an integration with angular where the tooltip displays currency formatted data.

Can you only leave the changes in src/cal-heatmap.js ? Other files will be built automatically on new version release
