Make the chase cam collide with environnement

[GoogleCodeExporter]

The chase cam goes through the environment.
Someone (sorry i don't remember who) contributed a Physics chase cam here 
http://pastebin.com/DVv59YSq
based on ray casting.

Normen suggested that we use a combination of CameraNode, PhysicsNode and 
ChaseCamera.

Got to setup a proper test case, and maybe a helper class.

Any news on this? My game will be unplayeble without this improvement.

Well if you're in a hurry, grab the pastebin code and use it. It works.

I did that, but I'm contributing to the JME. I started the conversion to the 
new camera API to make it more efficient. Sometimes it also doesn't stop before 
the terrain, so it goes inside it a bit. When I'm done I'll post it back.

This will take longer than I expected =\

The only problem now is that the camera is changing it's position when the 
physics calculation are applied. I can't visualize where's the error. If 
someone could gimme a hand here.

You might want to post it in the forum.

Oh sorry, I almost fixed it all. Now I'm trying to make it extends the 
ChaseCamera and work correctly. Let's see if I have any luck, because some 
methods of ChaseCamera I needed are private and not protected.

I wrote my own camera like this before I found this issue. Just a tip: One 
problem with the approach in Shirkits & the pastebin version that I found in my 
implementation is that it still clips the terrain if the camera is in a valley. 
I added ray tests in my version for the near frustum lower corners projected 
into the world. It works for my use case (I can ignore ceilings and some other 
things).
