[jdom-interest] add getFactory() method to SAXBuilder

[Nicholas Sushkin]

I noticed that JDOMResult has both
setFactory(JDOMFactory) and JDOMFactory getFactory().

However, SAXBuilder only has setFactory(JDOMFactory), lacking
JDOMFactory getFactory(). Would it be possible to add the missing method?

I really wanted to do jdomResult.setFactory(saxBuilder.getFactory()) ;)

Thanks!
