Work in progress

This is a snapshot of a work in progress.  Adds new SPI to WebView for putting the view into a "view source mode".  This will cause HTML and XML documents loaded in the view to display syntax-highlighted source by default.  The plan is for XML to also do this when it detects it is unstyled and for CSS/JS to do it all the time.

This patch also adds an HTML extension, a viewsource attribute, to iframes and frames, allowing Web site authors (or WebKit applications thate use frames) to show raw syntax-highlighted source as well.

Patch that gets basic highlighting working.

This patch gets basic highlighting working.  There are still many open issues, but this is a good first cut to land.

Open issues include:
(1) Loss of the whitespace in between tags and attributes and between attribute names/values.
(2) Entities need to be preserved.
(3) Scripts and styles don't work.
(4) Comments need to be preserved (this should just be done always).
(5) The DOCTYPE is lost.
(6) The bogus "/" attribute for faux XHTML has to be sent through in view source mode and treated like it's part of a tag.

... and there are probably numerous other issues...
