[SUGGESTION] Modify Ultimate Machine's text

[romqrocha]

Is your feature request related to a problem? Please describe.
When I have <1500 gold and I try to ultimate an already fully ultimated gun, it outputs "You cannot afford this item!" This implies that I would be able to upgrade my gun further if I had the gold.

Describe the solution you'd like
Make it so the code checks if the gun is already ultimated before it checks your gold. Then, even if you lack gold, it should say that your gun is already fully ultimated.
