Eliminated redundant wxRichTextAnchoredObject class; refactored XML I/O code

so that objects can stream themselves; added a wxXmlDocument-based method
of writing XML, though this turned out to be much slower than writing directly
so the direct approach is retained and is the default (can be changed with wxRICHTEXT_USE_XMLDOCUMENT_OUTPUT).
Loading and saving new attributes implemented. Added custom properties to objects.
