Added two convenience functions to QXmlStreamReader

QXmlStreamReader::readNextStartElement reads until the next start
element within the current element, or returns false when no such
element is encountered before the end element is reached. It simplifies
the common case of iterating over the elements in an XML document.

QXmlStreamReader::skipCurrentElement reads until the end element of the
current element, skipping any child elements. This functionality was
requested in two tasks, and a similar function 'readUnknownElement' was
present in Qt's stream reader example.

Autotest is included, example and documentation have been updated.
