Parametric box with label and rounded edges

Remix of acker's Parametric compartment box with lid (https://www.thingiverse.com/thing:15113)

I added the ability to select rounded edges both inside and outside. And I added a label that you can customise at the side of the box. I also adjusted the code to make it more compatible with the Thingiverse customiser.

But even if the code now is pretty compatible with the Thingiverse Customiser I would recommend to download the SCAD file and do everything in OpenSCAD on your computer. That wil
