This commits tweaks the material orange theme to use the exact color hue
of Jackys footies. To match this and give a slightly better contrast we
also change Jacksy border and logo text color to a slightly darker tone.
The original logo.svg is retained for reference, the new logo is logo2,
which all the .png variants have now been updated to.
