Suggested fix for use with WPML

I had some problems with wrong language versions of events showing up in the public calendar (using WPML). After a long time of searching, I found that the (object) caching seemed to be the problem since it didn’t consider the language.

My fix in event-organiser-ajax.php, around line 100:

//In case WPML is enabled. Include locale in cache key.
	$wpml_code = defined('ICL_LANGUAGE_CODE') ? ICL_LANGUAGE_CODE : '';

	//In case polylang is enabled with events as translatable. Include locale in cache key.
	$options = get_option( 'polylang' );
	if( defined( 'POLYLANG_VERSION' ) && !empty( $options['post_types']  ) && in_array( 'event', $options['post_types'] ) ){
		$key = 'eo_fc_'.md5( serialize( $query ). $time_format . $wpml_code . get_locale() );
	}else{
		$key = 'eo_fc_'.md5( serialize( $query ). $time_format . $wpml_code );
	}

I hope it can be implemented in the plugin.
