Restore the assist icons when a builder is selcted

[djtrame]

When the mod is active and you select a Builder, you don't see the icons there to assist you in selecting what you should build. For instance you'd see a farm icon, a mine icon, a Seaside resort icon, etc. Those are gone with the mod active.

In the future, I suggest using the issue search. You would have seen that this is documented in ticket #134. Just to reassure you: there is currently work being done on this in PR #412
