Uses new version of HtmlSpanner
Fixed bug where beforeChildren() wasn't called.

The AnchorHandler wraps the handler for p and h tags, but it
didn't called the beforeChildren() method of the wrapped
handler, leading to rendering errors in some cases.
Added config for extra fonts.
Merge branch 'font_rendering'
