XML

[ruan at jcell.co.za]

I have added some limited XML support in playground,
It has no language support yet, as I have not had time to learn the DUChain 
yet.

What it has so far:
1) A bad implementation of an XML tree view / Document
   Different models for XML and XSD. When the concept/features is finalized
   will add for SOAP and WSDL too.
2) Validator DTD and XSD (using libxml)
3) 4 formatters, actually only 2 with positive and negative formatting.

Let me know if there are any feature's that does not work or should be 
changed.

Outstanding:
1) A schema/DTD catalog. This can be used in language support and validation.
2) Language support.
3) And more here ... ;)

Thanks
