Java clients can now get material instances from renderables.

Browse Source 
Discussed this feature with Mathias, we decided to create
MaterialInstance Java wrappers on the fly, and create Material Java
wrappers lazily. This is simple and avoids caching the wrapper objects,
which might otherwise lead to complexity and bugs.

Note that gltfio creates material instances behind the scenes, so this
feature is particularly useful for gltfio clients.
