Pretty XML

[felix-itz]

XML created by the tool looks like this:

<definition xmlns="http://workflow.opencastproject.org"><id>test</id><configuration_panel><![CDATA[something]]></configuration_panel><tags><tag>upload</tag></tags><operations><operation id="snapshot"><configurations></configurations></operation></operations></definition>

The tool could, in order to be easier to read by a human:

1. pretty-print the XML
2. print the tags before the configuration panel
3. write explicit version and encoding <?xml version="1.0" encoding="UTF-8"?> (not mandatory by the XML standard) to the XML file
