Increased polygon draw widths

Eagle uses the "width" setting of the polygon tool as the width of the lines it uses to "paint" the copper pours into place.  When you use 0 width, it uses tens of thousands of draws, resulting in large gerber files.  It can also cause DRC errors with the fab, since you're doing a bunch of draws on a copper layer with a 0 width aperture.

I've changed the width of the polygon pours to 6 mils.
