Bounding sphere rendering started [no material set to test]

|SOURCE|
[Common/BoudningSphere]
* Populated the vertex array and index array with what should be close to
  correct values (though it doesn't look like a sphere will be generated from
  this at the moment)
* As the shader set expects a position and ST co-ordinate, some of the
  vertices will be very incorrect
[Common/Game]
* The world matrix is rotating on the Y axis to better demonstrate the
  spherical nature of the bounding sphere
[Common/Renderer]
* Added a call to render a default bounding sphere after the G-Buffer has been
  displayed
* Temporarily disabled the G-Buffer drawing
