[1.8.1 FIXED] Spam clicking through the add player dialogs in Hotseat games creation - more than 4 characters

To be clear, this only happened once and I can't get it to work again. But what happened was the following - I started a 4-player hotseat game to help verify another bug, and just spam clicked through the character creation process. But this time I noticed it kept going and going! "Player 8"??? never seen that before! It was auto-filling traits and moving to the next, but never allowing the game to start. I went to player 20-something, but the game never started until I back out of them all and returned to player 4.

When the game started, players without poverty had their inventories full of gear and there was an enormous amount of gear on the ground that was dropped due to no inventory space (from the failed players' starting inventories, presumably?)

In any case, I tried to reproduce it again but have not been able to, so unless someone else confirms it, it seems to be a fluke. Quite possibly yet another symptom of this old laptop's hard drive being about to fail.

I was unable to reproduce this, but I've added additional checks to prevent this from happening again.
