Frustum: Revise code and its Plane definition to support Cube->Frustum as well as to extract planes for float[] vec4-shader uniforms.

commit 1040bed4ecc6f4598ea459f1073a9240583fc3c3 added AABBox -> Cube -> Frustum mapping (incomplete)
and requires Frustum.Plane.set(..) by normal and point-on-plane for distance.

Frustum.isOutside(Cube) has been added, testing all its 8-points similar to AABBox.

Further all 6 Frustum.Plane shall be extracted to Vec4f and float[],
the latter to pass the whole float[4*6] as a vec4[6] uniform array to the shader.

+++

Constructor, setter and getter have been adjusted accordingly.

Most of the loops have been unrolled.

+++

Method names to query Frustum, i.e. 'is*Outside(<Type>)'
have been reduced to 'isOutside(<Type>)'
where <Type> uniquely indenticates the purpose.
Hence only 'isSphereOutside()' is left over.
