Feature/model node animation

[Roxeena]

This makes it possible to add a transformation to an internal model node for a 3D model. This also requires all nodes to store the name, therefor the caching format has been updated. The user can choose to either replace the existing transformation with the custom one or add it on top of the existing one with a parameter.

EDIT:
There is also a new function to print the model tree to help with finding the correct names for nodes to apply a custom transformation to.

Pull request overview

This PR adds support for addressing model nodes by name and applying custom transforms to internal nodes, including cache/binary format updates to persist node names.

Changes:

• Bumps model/cache versions and serializes/deserializes node names.
• Stores Assimp node names in ModelNode.
• Adds custom node transform APIs and applies them during rendering.

Tried to use this, but it did not work. The objects were not in their expected places.
