Add WIP version of the BLENDER importer. DO NOT USE FOR PRODUCTION YET!

Browse Source 
Loads static meshes. Sometimes (it segfaults on the rest). No materials, cameras, fancy stuff. Works with all versions of blender. No compressed blend files yet.

- StreamReader now uses shared_ptr's to manage ownership of the stream.
- Adapt other loaders accordingly.
