Fixed Waist, added save button, added arrows to press for rotation, backfaceculling

- Added a save button, not functioning yet but the art is there.
- Added arrows so user can now rotate the player without the mouse
scroll wheel.
- Added camera Photo button and save button to the menu transitioning
sequence.
- Tweaked body scaling so there is no clipping, changed some values so
extrusion works the best.
- Change waist scaling so the 32 size is skinner, looks like what a 26
was.
- Changed body slider algorithm for scaling so now the arms and hips
look better when weight is scaled.
- Added little snippet to extrusion shader that gets rid of backface
culling problems. Before you can see through the material if you were
looking at the back side. Now it is not transparent, a dark grey color
fills it in.
