Added a mint flavor skintexture to the ice cream sandwich.

Due to popular request, I smoothed out the models a bit so they look less like they're from the N64 era. I updated the logo and the first image so you can see what they look like now. Didn't change the in-game screenshots because I'm a scumlord.

I did not fix the weird textures around the edge of the pint of ice cream and on the cherry of the ice cream, because I have no idea why they're weird. They don't look messed up to me in Blender, only in GMod. Will update if I ever figure it out.
