Chiba 0.9.8 released

This release further improves Chiba's conformance to the XForms Spec, namely the full support of the Submission module, improved namespace handling in XPathes, basic support for the Range control as well as refinements and extensions to Upload handling. The XMLRPC connector package has been extended and now provides a URIResolver/SubmissionHandler pair and a sample server. As always some tests have been added and dead parts have been removed.
