WorkItemRecord.toXML() returns invalid XML when taskName or documentation contains &

[mlawry]

This is similar to issue #614.

WorkItemRecord.java's toXML() method calls:

xml.append(StringUtil.wrap(_taskName, "taskname"));
xml.append(StringUtil.wrap(_documentation, "documentation"));

When _documentation contains '&' the output is invalid because it is not escaped as &. Same goes for _taskName.

May be should use StringUtil.wrapEscaped instead of StringUtil.wrap.

May be all wrap calls in WorkItemRecord.toXML() method should use StringUtil.wrapEscaped?

Fixed and in repo.

Most data is already escaped elsewhere, only necessary to do data members as required
