Minor bugfix release

Some fixes related to issues with the recent game engine improvements. And some fixes for issues that were there before. And, as usual, a couple typos.

I have to say I'm pretty happy with the rollout if the game engine improvements, most of the issues are pretty minor.

I received several crash reports on my Discord server, so thank you to everyone who sent those.

Biggest fixes:

• The sound library is a little less robust than the old one, and I realized that was leading to crashes in some circumstances. I added a fix.

• There was a (probably) longstanding issue where you could just walk into the Baron's Chateau without proving to the guards that you were a University of Chingaim graduate, this is fixed.

I would like to explain the second issue a little more. Before this fix, you didn't actually have to talk to Deiter and Werner, the guards blocking the door to the Chateau. You could just walk past them up to the door, and icon would change to say Open, and you could go in. This was not deliberate (however it is kind of funny that all kinds of people played the game and went through all kinds of trouble to get a fake degree form the University, when they could have just walked right in).

This issue wasn't in the game at the original release. When I released the game, I had made sure that the proximity to Deiter and Werner had higher priority than proximity to the door. Basically, wherever you are standing affects the current action. If you are standing near a door, the current action may be to open the door (and the label on you action button will read "Open"). If you are standing near a person, the current action may be to talk to the person (and the label changes to "Talk"). If you are standing near both, one of them has to take priority (you can't have two current actions at once). When I released the game, I had made sure Deiter and Werner always had priority over the door, so you couldn't enter the chateau until they moved aside.

At some point, and I am not sure when, this changed. Some circumstance in the code, changed and the door had priority. At that point, anyone could have just walked in.

This change fixes that, and furthermore it doesn't rely on priority any more, the door (almost) isn't a real door until you have the degree in your inventory.

I actually considered leaving it in, because it is kind of funny. The main reason I decided not to is that, if you enter at the wrong time, it can softlock the game.
