no longer use hacks gbxmltitle and gbxmllinks.
no longer convert html entities for xml docs using hacks
since we have XmlDoc::hashXmlFields() function.
added qaxml() qa test to test xml doc indexing and searching.
ignore <?xml> tag when generating xml tag compound name.
xmlnode in the Xml.cpp class. hopefully
will not get "malformed sections" error
anymore. i think that was a result of the
json having html tags in it and making
unnested html structures which the
sections class did not like.
TODO: probably do this for CT_TEXT etc.
as well.
