        Fix XPath test suite conversion problems

        * dom/svg/level3/xpath/svgunit.js: Fixed createXPathEvaluator() to work in Firefox (whose
        document.getFeature returns null for XPath). Changed load() to use XMLHttpRequest, instead of
        merely cloning the current document.

        * dom/svg/level3/xpath/resources/internaldtd.xml: Added.
        * dom/svg/level3/xpath/resources/staff.dtd: Added.
        * dom/svg/level3/xpath/resources/staff.xml: Added.
        * dom/svg/level3/xpath/resources/staffNS.dtd: Added.
        * dom/svg/level3/xpath/resources/staffNS.xml: Added.
        Added external test documents.

        * dom/svg/level3/xpath/XPathEvaluator_evaluate_WRONG_DOCUMENT_ERR-expected.txt:
        * dom/svg/level3/xpath/XPathExpression_evaluate_WRONG_DOCUMENT_ERR-expected.txt:
        These tests now run, but fail. They also fail in Firefox, but pass in Opera.

        * dom/svg/level3/xpath/XPathResult_invalidIteratorState_ANY_TYPE-expected.txt:
        * dom/svg/level3/xpath/XPathResult_invalidIteratorState_ORDERED_NODE_ITERATOR_TYPE-expected.txt:
        * dom/svg/level3/xpath/XPathResult_invalidIteratorState_UNORDERED_NODE_ITERATOR_TYPE-expected.txt:
        * dom/svg/level3/xpath/XPathResult_iterateNext_INVALID_STATE_ERR-expected.txt:
        These now fail, because XPathResult relies on DOMSubtreeModified event for invalidation,
        but event listeners cannot be registered on nodes in documents that aren't attached (such as
        XHR.responseXML). Not yet sure what exactly the bug is, but I think it's good to have the tests
        fail, as it appears to be a genuine issue.

        * dom/svg/level3/xpath/XPathResult_invalidIteratorState_ANY_TYPE.js:
        * dom/svg/level3/xpath/XPathResult_numberValue.js:
        Updated these tests to use /staff instead of /svg paths.

        * dom/svg/level3/xpath/XPathResult_iteratorNext_ORDERED_NODE_ITERATOR_TYPE-expected.txt:

        * dom/svg/level3/xpath/XPathResult_stringValue-expected.txt:
        These tests now pass.
