I submitted a patch at some point for adding pay to bypass cooldown using Economics.  Somehow that made it in but I don't see any documentation for it, and iirc the version is the same.

Basically for each config section where you want to enable this, you can add something like this:

"Home": {
  ...
  "Bypass": 2
  ...
},
​

This would require a payment of 2 coins from the player's balance to bypass the cooldown timer.  This should work for home and town.  I don't believe it was added for anythying else.

Actually, it appears that this may have been partially implemented.  I don't have older versions available to see.  But, I plan to add that functionality.
