The Accessible interface is cool but it lacks a method to programmatic-ally get a list of all the keys, just in case you need to show the configuration in any different way from the basic list mechanism already present

👍 pretty easy, I'll do that asap. I will return a "snapshot" of the keySet, not the keySet itself as returned by Properties.keySet(). I think it should be fine too, and will prevent unchecked modifications (thread safety, etc)

implemented change req. #46 propertyNames()
b93b2f0 
in interface Accessible

    Set<String> propertyNames();

This differs from the correspondent method in java.util.Properties
since Properties.propertyNames returns an Enumeration<?> but property
names are required to be Strings. In JDK 1.6 the method
`Set<String> stringPropertyNames()` has been introduced but since
we require JDK 1.5+ support I couldn't just delegate and I had to
reimplement it. So I chosed to implement it with the proper method
signature, even though it doesn't match java.util.Properties
interface.
