A simple addition that adds Egg's sell value to its description.

Thank you! Great idea!! Just one thing: this can be done easier without needing to keep track of the sell value separately by referencing the sell cost directly on the object like this

create_display_text_object({ ref_table = self, ref_value = "sell_cost", colour = G.C.GOLD })

Can you modify that so I can merge?

Done!
