Add support for outputting the AST as XML

[GoogleCodeExporter]

I've made some enhancements to enable the dumping of an AST to XML or a 
JSON-style structure (this is not necessarily JSON compliant). 

I found this useful when trying to create AST from scratch. I figure it might 
be useful to someone else too.
