Okay, this one got messed up, a lot of commits got included. This wasn't my intention.

Anyhow, the automatic configuration binding by field name is something like this:

class AutoBindExample {
  // Will be assigned from name=JohnDoe
  @Configuration 
  String name;

  // Will be assigned from user.name=JohnDoe
  @Configuration("user.") 
  String name;
}

On the other hand SystemConfigurationProvider has been simplified, it's actually a specialized PropertyConfigurationProvider where the Properties are coming from System.getProperties();
