[jdom-interest] Factories for builders.

[Paul Philion]

Ken -

I always prefer an interface (call it ElementFactory, for example) and a
default implementation (DefaultElementFactory). SaxBuilder could have either
a setElementFactory or an additional set of constructors (each having an
extra parameters: ElementFactory). Typical behavior would be to subclass
DefaultElementFactory and override the specific behaviors that you need.
