Temperature tower remix

Added letters A to I to this nice temp tower. That way you can use whatever range you prefer. I also added a small break-off tab so you can get a feeling of layer adhesion. Not sure how well that will work, though.

Remember to always set the highest temperature on the bottom (A) section. That way you get better bed adhesion and if your lowest temp is too low to extrude, it will be at the top.
