CrosseyedRenderer is a hack, camera must have target :S.

Aargh, I feel dirty now.

This one was quite a pain.

Got stuck on the PathCamera/PathControls one. Maybe it's time to rewrite this...

This will take a while to make work again... probably needs some cleaning and refactoring...

I could have just used `lookAt( scene.position )`, but eventually I would like to have Scene not extending Object3D.

* Camera is now a base object. PerspectiveCamera should be used instead. Figured out a way to show a warning when misused.
* OrthoCamera is now OrthographicCamera.
* Removed `target` from Camera.

Misc
* Renamed Trident to Axes.

SubdivisionGeometry now uses parent's geometry colors and materials (and UVs). but what do we do with vertexColors?

Seems like calling `renderer.initWebGLObjects` out of regular frame render doesn't play well with new buffer switching minimization optimization.

Found out that CrosseyedWebGLRenderer probably wouldn't work for target-less cameras.
Something weird going on with `webgl_scene_test.html` and `webgl_scene_test_blender.html`. For some reason cubes dissapear.

Removed QuakeCamera.
