added funtion for the golden eggs(1.5b)

i believe there should be a stable form of currency that has more than one use.
for example if 25 golden eggs are also necessary in order to make a msi, then there would be an incentive to keep on collecting/trading the golden eggs.
as of now i believe they only serve the function of storing mesos and therefore useless to farm after you have like 10 eggs.

just throwing that out there

thank you for reading

Agree.
