Open Source Hardware logo module for OpenSCAD

My first module for scad.

Usage :
* oshw_logo(h, w, res=4); // display line oshw logo
* oshw_fill_logo(h); // display fill oshw logo
* oshw_text(h); // display oshw text on 2 lines

where :
* h = object height, example 5
* w = line width, example 1.0
* res = cylinder face number object in line drawing (default 4)

Logo size is 10 by 10 centered on X and Y axis. Height start from 0 to h value along Z axis
