FullCalendar event additional styling options

Hi
I found this solution useful when I required to target styling precisely for particular events in FullCalendar view;
this is a ready-to-take mod rather than a feature request , yet it would be nice to see it in the upcoming update.

So, in events-maker\includes\shortcodes.php I amended this function a bit:

function get_calendar_events($args)
	{
		$events = em_get_events($args);
		$calendar = array();

		if(empty($events))
			return $calendar;

		foreach($events as $event)
		{
			$id = $event->ID;
// mod start
			$catClasses = array();
			$aCategories = wp_get_post_terms(  $event->ID, 'event-category');
			$aTags = wp_get_post_terms(  $event->ID, 'event-tag');
			
			if (count($aCategories))
				foreach($aCategories as $category) {
					$catClasses[] = "fc-event-cat-" . $category->slug;
					$catClasses[] = "fc-event-cat-" . $category->term_id;
				}
				
			if (count($aTags))
				foreach($aTags as $tag) {
					$catClasses[] = "fc-event-tag-" . $tag->slug;
					$catClasses[] = "fc-event-tag-" . $tag->term_id;
				}
// mod end
				
....

Then in the events array assembly I added this line:

$calendar[] = array(
				'title' => $event->post_title,
				'start' => $start,
				'end' => $end,
				'className' => implode(" ", $catClasses), // <<<< added line
				'allDay' => em_is_all_day($id), 
				'url' => get_permalink($id)
			);

This is arg described in FullCalendar documentation.
This gives me some additional classes in the list of rendered events, like that:

...<a href="http://some.url/" class="
fc-event fc-event-hori fc-event-start fc-event-end
fc-event-cat-zajecia-oferta-stala
fc-event-cat-118
fc-event-tag-dzieci
fc-event-tag-182
fc-event-tag-gimnastyka
fc-event-tag-180 ... " style="...."> ....

Now, I’m able to add i.e. different colors for events under different categories, assign icons etc.
Ofc it will work as soon as you have an event assigned to any event-rlated taxonomy (categories or tags).
