Introduce a clear distinction between internal exceptions and
user-visible exceptions, leaving AFPException as base abstract class.
Later, it should be possible to narrow some types around, e.g. in
ParserStatus (that might work with user-visible exceptions only).
Also a future TODO is putting all the exceptions in their own namespace
(probably ...\Parser\Exception).

Thanks to this, we will be able to provide more information
to consequences and watchers, which will open door for new
features and possibly cleaner code.
