v1.0.47

Bugfixes:
* a memory leak someone reported through in-game feedback! Thank you anonymous person!
* getting sacked by pirates while carrying non-sellable goods (Old Sailor, Ambassador) would result in the game crashing because the game could not determine the value of the goods 🙂 Pirates will now no longer try to take these non-sellables from your ship.
* the Busy Bee campaign would not correctly register reaching 12 ships if they were obtained through fighting pirates and not through building in shipyards
* you could not repair your ship for free (following event) if you had negative balance.
