scale_x and scale_y for sprites

[GoogleCodeExporter]

I wanted to scale sprites independently across the x/y axes. To accomplish this 
I patched sprite.py to include additional scale_x and scale_y properties. 

Internally, _scale_x and _scale_y replace _scale, but the scale property is 
still available. It sets both _scale_x and _scale_y at once, but returns only 
_scale_x. I made a note of this in the scale property documentation. 

I noticed this feature has already been patched by another user, but it wasn't 
followed through with because they posted dead links.

Thanks.
