Enhance main menu map (3D Front End)

[tonihele]

Enhance main menu map, well technically the special hero gate. Before any major graphics overhaul. We could:

• Use real point lights in the candles
• Tryout the JME god rays instead of light beams (just try... maybe not the smartest move)
• The hero gate peaces are static and never deformed -> texture maps, bump mapping...

Would provide a nice modern impression.

Related, main menu now has torches :) It really doesn't need to.
