Visible error messages

[Luiji]

#419 shows something annoying about TSC right now: non-fatal warnings are printed to the console, which almost always only the developers have access to. We should have a graphical method of displaying these in-game so people don't have to restart the game in a terminal and inspect logs.

I wouldn't like a message box because if somebody's fine with e.g. broken audio they won't want to click "Continue Anyway" every time they start the game, so perhaps a fairly visible prompt at the top would be nice.

Actually, the game occasionally does display errors to the user using a method of the HUD class. You can try this for example by corrupting a savegame file and then trying to load it. It will print an error message both to the console and show one to the user. The one on the console is more detailed, but that’s probably correct.

Vale,

We now have the game scripting console -- this could be the best way to display errors. However, the game scripting console is only available in levels.
