API change! This actually makes the bearing code usable sice it works around a bug in openscad that prevented using the code easily

Testing seems to work. Adding () after a function does wonders if you want that function to actually do anything (like flush the testing code to disk so that openscad actually has something to chew on ;)

Conflicts:
	triangles.scad

just found out that there are 2D primitives too, no need to use DXF... so changed the triangle to use polygon and extrusion, cleaner than doing weird booleans.

This changes the default orientation of the triangle so adapted the servo library too.
