[Inkscape-devel] icons restored

Since icons can be easily changed via the new theme support, I've restored the z-order, flip, and calligraphic icons to their original state, to maintain the 0.40 look. I think if we're going to _change_ existing icons, it should be subtle (adjustments) or whole-sale (total replacement of everything). Any personalized tweaks can be done via the ~/.inkscape/icons/icons.svg file.
