Expose internal date and add support for events in calendar view

[jeffhuys]

Exposing the internal date object I've added support for exposing the internal date object of the calendar view. You can use this as follows:

<div pickadate ng-model="calendarDate" current-date="calendarCurrentDate"></div>

Now, calendarCurrentDate will be the Date object of the calendars' current view. For instance, when the user sees "December 2015", and calls calendarCurrentDate.getMonth() it will return the month number.

Showing events on the calendar I've also added support for supplying an array with formatted dates to show in the calendar. Use it like this:

<div pickadate ng-model="calendarDate" dates-with-events="calendarPopulatedDates"></div>

In my case, I've added dates like this:

// Get all events from the API
Event.getAll(function(events) {
    console.log('Events retrieved', events);
    $scope.events = events;

    // Add every event to the calendar
    events.forEach(function(event) {
        var date = new Date(event.begin * 1000);
        var year = date.getFullYear().toString();
        var month = (date.getMonth()+1).toString();
        var day = date.getDate().toString();

        $scope.calendarPopulatedDates.push(year + '-' + (month[1]? month : '0'+month[0]) + '-' + (day[1]? day : '0' + day[0]));
    });
});

Note: this may not be the most efficient way to do this.

It looks like this:

The build seems to have failed. I've updated the code.

EDIT: If someone could help me out with parsing the errors, I'd appreciate it.
