Core/Chat: Allow GameObjects to use various talk functions.

Also includes a re-instating of a hacky fix, namely Mr. Smite in Deadmines shouting an alarm.

Note, they are the same as normal talk functions as provided for creatures. There is no actual behavior for gameobjects as it seems, however this allows some customization and/or hacky ways to do talking GOs.
