SVG without height and width

[msetina]

Is there a possibility to make SVG without width and height?
Height and width are there just to make a size of the image, but SVG is a scalable (it is in the name). ViewBox is there to make the internal size. Externally it would be nice to fit it into the requirements of the external environment.

#413 addresses this issue. Since it changes how QRCodes are rendered in the browser (without CSS constraints) its backwards incompatible, so it must be part of a Major release, not minor. I'll see if I can make a 9.0 pre release.
