0.9.8 released

A great many changes, mostly to the parser logic. If you've been using the CSS interface, then you really should upgrade to this, since many bugs have been fixed (see the changelog for a big list).
Also, some parts of the HTML parser have been improved, particularly in the parent elements function, where it would have trouble in some cases with badly nested block elements.

If this doesn't work for you, please let me know (geoff@accessware.co.nz). This release has been tested on 300,000+ pages, and should be ok, but I'm open to ideas.
