Inlined the OpenGL access methods, also renamed some of them to make the names more durable in case the official methods are promoted.

Split OpenGL extension stuff into new file which is inherited by the driver in order to keep backward compatibility. The handler is not automatically created and thus has to be manually updated sometimes. Many functions and pointers are still missing...

Removed array::erase from loops in Octtree.h and COctTreeTriangleSelector.cpp, they now generate a lot faster.

Fixed Ogre file format check to support new version. Fixed some missing inits. Changed some tests to switch statements.

Cleaned the MeshCache interface, added filename methods from CMeshCache to the interface. Also changed the Scenemanager interface to accept IMeshCache instead of CMeshCache.

Made the MeshBuffers be based on a template class. The original headers do still exist for compatibility reasons. The SMeshBuffer... structs are now typedefs of the template.

Started to make matrix4 a template to allow for better adaption. Due to renaming of the template the original matrix4 type is still the f32 version of the matrix. I had to remove some forward declarations, though as I did not want to add the template declaration into other headers.

Reverted the frstum culling test to the old one which was fine, except for the wrong usage of isFrontFacing...

Fixed the texture mapping of the sphere scene node. It is now wrapped by one texture without artifacts. Also made x and y subdivison separately adjustable when calling the constructor manually.

git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@669 dfc29bdd-3216-0410-991c-e03cc46cb475

Enhanced documentation for isFrontFacing to make it safer to use. Fixed frustum culling to correctly handle all possible cases of box intersections. Replaced isFrontFacing by classifyPointRelation as suggested by vitek. Minor cleanups in some classes.

Replaced some f64 by T in container classes, where computations were only f32 correct anyway.
Made triangle3d.isOnSameSide private as it is completely unrelated to triangles.
Renamed plane.existsInterSection to plane.existsIntersection since all other functions concerning intersections use the small s.
Fixed plane3d.classifyPointRelation to return the correct relation. Spotted by vitek.

More fixing of Sphere texture coords. Now we have proper spherical mapping, but a weird seam at the date line - when using the earth.bmp.
