Don't let path_breadcrumbs_breadcrumb escape the title

The title is escaped by the breadcrumb mechanism of drupal before it is sent to path_breadcrumbs_breadcrumb.

When you use Knockin' in a title, it is modified by the link function. This happens only when PATH_BREADCRUMBS_RICH_SNIPPETS_xxx is not used, for in those cases the $options html key is set to TRUE (already).

My suggestion is to make $options['html'] TRUE by default at the top of the function.
