Changes

Introduce URI scheme 'binref' to allow referencing BinaryResource

An URI with scheme 'binref' identifies a BinaryResource. The utility
class BinaryRefs provides methods to get the BinaryResource reference by
such a URI. An application must create classes implementing
'IBinaryRefHandler' in order to load a BinaryResource for a URI. A
handler registers itself for a path. If a (prefix-)path of a binref URI
matches the registration path of a handler this handler is called to
load BinaryResource for this URI.
