Related posts hook into other custom post types

Hi Barry,

Nice plugin! I really like the relevance for the selected posts which becomes visible below my blog posts.

I found a small problem:
On my websites I use Coen’s plugin “Smart WYSIWYG Blocks Of Content” to show small content blocks in the footer widget area. I guess your plugins hooks into the content using the is_single() condition? Seems like there is conflict with the custom posts from these blocks, because the related post become visible for these ones, too.
I’m using this filter now
add_filter( 'rp4wp_append_content', '__return_false' );
but I think this bug might be problem for other custom post types that are used on the same page, too.

One suggestion: please add support for custom templates, would be great to use my own HTML and Bootstrap CSS.

Thanks!
