JSON parse error

I’m trying to use your plugin, but the front-end stuff won’t work due to a JSON parsing error.

On line 109 of assets/js/frontend.js you have the following:

var useCustomStarImages = jQuery.parseJSON(mr_frontend_data.use_custom_star_images);

The mr_frontend_data.use_custom_star_images is an empty string, and it throws a very useless error Unexpected end of input.

The reason it gets an empty string is because on line 437 of multi-rating.php, you’re getting the setting with 'use_custom_star_images' => $style_settings[Multi_Rating::USE_CUSTOM_STAR_IMAGES]

If you switch it to 'use_custom_star_images' => $style_settings[Multi_Rating::USE_CUSTOM_STAR_IMAGES] ? 'true' : 'false' so that it actually outputs ‘true’ or ‘false’, then the JSON parsing stuff won’t break.
