Suggestion: Testing for 0

Hi, scribu,

I was using your plugin to output a rating from 0 to 10. When the rating was 0, however, the plugin was invoking the placeholder function due to PHP’s handling of a string of 0 as empty. I hacked mine like so to output the value:

protected function placehold( $content ) {
		if ( empty( $content ) )
			if ($content === '0') {
				return $content;
			} else {
				$content = $this->placeholder();
			}
		return $content;
	}

I also hacked the version to output non-breaking space characters   instead of [empty]. Perhaps the output of the placeholder would be something the should be settable in the plugin options.

Again, great plugin and thank you for the support.
