Create a rolling-dice example

[Makman2]

• Create a die-model
• Load multiple dice
• Set up physics
• Throw the dice

To make the example better looking, the hybrid renderer from #63 is required.

We could try to use Bullet Physics SDK, commonly used and written in C++. For prototyping and testing, Python is also supported.
