Removes all use of COM and dependencies on Windows-specific classes (including the use of AccessibleBase and AccessibleDocument) in the glue accessibility implementation.Introduces the GlueAccessibilityObject, which serves as a platform-independent wrapper directly around WebKit's AccessibilityObject (also platoform-independent).Updates naming/comments to reflect the independence of IAccessible both in glue and (where appropriate) in the browser-side accessibility.
