Create better quest details graphic

Right now, the quest details graphic shows a pie graph which sadly is usually just a solid circle and ergo useless and boring.

Instead, let's draw out the fate chain like we do in the fate explorer and then show how many labors are at each of the various points on the chain.

Start by locating the quest details graphic that renders the current pie graph, then read the fate explorer implementation to understand how it draws the fate chain. Replace the solid-circle-prone chart with the chain layout and show the number of labors at each point; done means quest details clearly expose both the chain and its labor counts.
