Title: Using platform's default XMLReader

Piccolo implementation of SaxParser have encountered some edge cases
where it goes into an infinite loop and eventually fills up the heap.
Platform's default parser are more stable and with unnoticeable
performance difference.

One can configure it's platform to still use Piccolo if desired, also,
Piccolo is used if it cannot find a default XMLReader implementation.
