[Mini-bugs fix] undefined variables and such

Hiya, when upgrading I did a quick check for any changes I might have made to the code myself and found that I fixed the below. I hope you’ll accept these fixes for the plugin core code.

Hope this helps,
Smile, Juliette

File: mcm_view_custom_posts.php

Find line 228:

<div class='mcm_posts $primary $display'>
		$front
			$return
		$back
		</div>";

Replace with:

<div class='mcm_posts $primary $display'>
		" . ( isset( $front ) ? $front : '' ) . "
			$return
		" . ( isset( $back ) ? $back : '' ) . "
		</div>";

File: mcm_widgets.php

Find line 86:

$post_type = esc_attr($instance['mcm_posts_widget_post_type']);
		$display = esc_attr($instance['display']);
		$count = (int) $instance['count'];
		$direction = esc_attr($instance['direction']);
		$order = esc_attr($instance['order']);
		$title = esc_attr($instance['title']);
		$term = ( isset($instance['term']) )?esc_attr($instance['term']):'';

Replace with:

$post_type = isset( $instance['mcm_posts_widget_post_type'] ) ? esc_attr($instance['mcm_posts_widget_post_type']) : '';
		$display = isset( $instance['display'] ) ? esc_attr($instance['display']) : '';
		$count = isset( $instance['count'] ) ? (int) $instance['count'] : -1;
		$direction = isset( $instance['direction'] ) ? esc_attr($instance['direction']) : '';
		$order = isset( $instance['order'] )? esc_attr($instance['order']) : '';
		$title = isset( $instance['title'] ) ? esc_attr($instance['title']) : '';
		$term = isset($instance['term']) ? esc_attr($instance['term']) : '';
