Type errors after the type hinting added.

In working with the newer version I've discovered that versions after 0.3.0 / 2bea304 consistently cause this error on my machine:

pl.danieljanus.tagsoup=> (lazy-parse-xml "http://google.com")

ClassCastException com.sun.xml.internal.stream.events.AttributeImpl cannot be cast to javax.xml.stream.events.StartElement  pl.danieljanus.tagsoup/xml-name (tagsoup.clj:182)
