shortcode display top rating show_count

Hello,

In the docs you have:
````
[display_top_rating_results]
[ .. ]
show_count – Do you want to show the count of entries. Default set to true. The count is only shown if the [ .. ]
````
however the code is set to force the show_count to always be true. While I do understand that this is ok and all, it should be allowed to be disabled no? At the very least docs says so :-/

Anyway, if you could push this in as an update for future release, will avoid me trying to adjust the code for it

Thank you for understanding and thank you for the wonderful plugin :)
