Scott Wells updated CONFIGURATION-342:
--------------------------------------

    Attachment: ConfigurationUtil.java

Demonstrates simple version of flattening/unflattening multi-valued property values for flat
key/value storage, e.g., to properties files, current database configuration tables, etc.

> I've found a bug where adding a list property to a BaseConfiguration, then copying that
full BaseConfiguration to a DatabaseConfiguration, the list is lost and only the first element
is copied to the destination DatabaseConfiguration.  For example:
> BaseConfiguration bc = new BaseConfiguration();
> bc.addProperty("myList", Arrays.asList("1", "2", "3", "4");
> DatabaseConfiguration dc = new DatabaseConfiguration(...);
> dc.copy(bc);
> List list = dc.getList("myList");
> // At this point, you'll get a single element list containing only "1"
