changes in namespaces

[Siarhei Barysiuk]

Hello,

To avoid conflicts with namespaces of previous version we decided to
add specific version postfixes to current NS.

Now namespaces should look like:

xmlns:qx="http://www.qxtransformer.org/qooxdoo/0.8" instead of
xmlns:qx="http://www.qxtransformer.org/qooxdoo"
xmlns:qxt="http://www.qxtransformer.org/extension/0.4" instead of
xmlns:qxt="http://www.qxtransformer.org/extension"

You can find the latest version of the toolkit with these updates in
our SVN. I also updated XSD in trunk/xsd folder and sample
applications.

Best regards,
