#6 Change default fallback wrappers

[Anonymous]

In org.ho.yaml.YamlConfig.getWrapper(String classname) (around line 300) you have hard-coded the handlers when no handler for a class is found, with a final fallback to DefaultBeanWrapper. It would be good to be able to configure these fallbacks, which would save having to maintain a list of handlers for a long list of classes. I can always hack the code which solves my problem, but doing this via the configuration strike me as a better solution.
