ID (anchor) generation

I’ve noticed you use sanitize_html_class in conjunction with get_the_title to generate IDs for the FAQs. This does not work like described in the Arconix FAQ documentation. For example, “Why are opening quotes not being styled” as the title of a FAQ entry results in the ID “faq-Whyareopeningquotesnotbeingstyled” instead of “faq-why-are-opening-quotes-not-being-styled”.

A solution would be to use sanitize_title_with_dashes, preferable in conjunction with the_title_attribute (because get_the_title can be filtered by other plugins and may contain HTML tags). If you’ve got a Git repository somewhere, I’d be happy to provide a pull request.
