Customizable Temp Calibration Tower

**Thanks to wstein's tip** Customizer should be working fully now!

I really liked [peke's calibration tower design](http://www.thingiverse.com/thing:729703), but wanted to test with different temps than he had. And was bored one day.

I feel like this is a good test print, and its still quite light (4grams for 7 layers I believe). Its also good for testing print speed.

Photo is printed at Layer Height of 0.1mm, using purple Inland brand filament. And the default label range is based on previous tests implying that higher than my normal print temp (208) might be better for it. (Wouldn't say its worth the $5 savings over Hatchbox which is what I've used previously)

tour_de_chauffe_v3 has suggestions from @Rockbert, and stole an idea from @puckett_jw's Make

Future plans (TODO): I should add a platform that you can add other notes to it... like 'layer height 0.1' et
