MSHTML: tighten up announcement of roles for some HTML5 tags where ARIA is used, and text nodes. Specifically: * text nodes now get a role of text (static text) rather than textFrame. * Text nodes can also now be reviewed again, by catching an exception. * NAV and SECTION tags now are mapped to a role of section, and ARTICLE is mapped to a role of document. Previously these were all textFrame or in some strange cases Edit!. This brings IE support inline with Firefox in these specific cases. Most importantly stops announcing all the content of these tags when focus moves inside them.
