Ok, we can return null. I will change the BooleanConverter to return null.
But if no converter is able to convert the value into the requested
target type we must throw an exception. We cannot suppress such an error.
WDYT?

To make it more clear how we envisioned the PropertyAdaptors to work:
E.g. we have Configuration.current().get("mykey", Boolean.class);
This would result in the following steps
1.) look up 'mykey' in all PropertySources.
2.) if nothing was found (val == null || null.isEmpty()) -> return null; and we
are done
3.) if something was found -> try to convert. Iterate over all PropertyAdaptors
until one of them could convert it
4.) if the value could not get converted -> ask all PropertyAdaptors which
format they support and log an error or throw an Exception even?

+1 please revert. This is a kind of fall-through loop. And only if none of the
PropertyAdapters knows the format we need to log some warning.
