icon: provide a symbolic variant of the app icon

since gnome 3.16 we're perusing the symbolic icon
for high contrast theme

Three problems:
* As <circle> is used, the icon do not work as a symbolic one (not highlighted in the topbar). Circles should probably be transformed in a path, as I did for Iagno’s symbolic icon.
* I find the dark color hard to read in the topbar. That’s the reason why, for Iagno, I continue to use the “white border” thing (but I probably do a bad thing letting one circle empty, even if there are not case where that could be seen for now; but that’s another story).
* The circle in the bottom of the second column should be dark, or the drawn position is not playable.

The updated patch solves the first issue (the technical one).

Review of attachment 300592 [details] [review]:

To be clear about what Arnaud was requesting: this patch reintroduces bug #677638, where there are two different lines of four circles of the same color in a row, which is not a possible game position. You can avoid that by swapping the color for one of the circles, preferably the second circle from the left in the bottom row, to match the highcolor icon.
