SVG-Edit-generated IDs can now sport a nonce (to uniquify them). The value of the nonce is recorded as an se:nonce attribute on the root <svg> element.

The default behaviour is as before. But, if you call svgCanvas.randomizeIds() or if setSvgString() detects an se:nonce attribute on the root <svg> element, this will trigger the new behaviour (in the latter case, using the existing nonce).
