Add updated gerber download code

[kr15h]

I do it again with new updates

[kr15h]

Just tested with text on silkscreen layers and it works in tracespace.io. It would be nice to have the original text available via global state so that one could take advantage of the Gerber X2 text markup (Gerber Spec p. 147).

[kr15h]

So I tried to design a board, export Gerbers and mill with CopperCAM. All works, except CopperCAM does not work well if pads are defined as polygons - it recognizes them as copper fills and it causes problems with layer alignment. I suppose that is no problem with tracespace as everything shows up there nicely.
