It required some minor additions to the engine code, but nothing too brutal.

Now more amenable to adding new gem colors.
Tirakai's Maul can have gem interactions defined easier.
Goedalath Rock now gives golems shadowflame damage.
Shadowflame damage type now has a text color.
Gems show their 'latent damage type' on tooltips.
