/** Example 021 Quake3 Explorer

This Tutorial shows how to load different Quake 3 maps.

Features:
	- Load BSP Archives at Runtime from the menu
	- Load a Map from the menu. Showing with Screenshot
	- Set the VideoDriver at runtime from menu
	- Adjust GammaLevel at runtime
	- Create SceneNodes for the Shaders
	- Load EntityList and create Entity SceneNodes
	- Create Players with Weapons and with Collison Respsone
	- Play music
