Add a confirm button

[AzkaS]

Hi! I have a request, if it would be possible to add a confirm button to Mijnlieff. Many games on BGA have this feature and it's very good to prevent misclicks. I have recently lost a few games of Mijnlieff just because of misclicks I accidentally made on my phone. And especially in the variant where the board is arranged by the players, it's really easy to do a misclick just when placing the board. Many thanks if you implement this!
