Add maxticketprice parameter

The maxticketprice parameter can be added to prevent the purchase of overpriced tickets

Not sure why you are calling the tickets overpriced. If anything, it's a highly subjective take.

I don't see any reason for this if you are using the autobuyer. We had a similar option before and removed it after the ticket price algorithm was changed to smooth out the crazy price spikes and drops.

If you are not running the autobuyer, you can buy them any time you want to manually, and again don't need an option like this.

I see that ticket prices have been fluctuating at an alarming rate recently. I think there should still be ways to support users in these volatile situations, or there should be a way to stabilize ticket prices in the future.
