Character Rotation, Environment Tweaks, Clothing Clipping

- Charcater can now be rotated by using the mouse wheel.
- Added some environmental tweaks, such as replacing the floor texture,
Adding different shaders to the floor (with cubemap), and different
color to the teal glowing lights.
- Created an extrusion shdaer and added it to males shirts (blazers and
shirts) so they extrude out a little when the waist size is increased.
This expands the clothing, removing most if not all clipping problems.
- Changed Cameras positionings so that it does not attach anymore to
character. Before, when this was possible, it would mess up the camera
view when rotating the character.
