Add a config setting to always re-create config files

It might be good to default this to on. This would allow the standard user to just get updates and have the player data, monster data, and localization data always update.

If someone wants to tinker they could turn it off.

I'd want to have solid startup messages to indicate the change.

I'm going to default to making a backup of the .json files and replacing them with the calculated version. I'll just add a message for a config option to "UseCustomData" to load user data files.

This will be a larger change than I expected since it loads all the config files at the same time. If it loaded the Config.json first and we could use those settings to dictate if we import the others do.

I'm not quite willing to add the hack needed for ConfigContainer to handle it.

I'll just settle for #10 to tell people to delete .json files after an update.

I changed my mind, the hacky approach is ugly but I think will work perfectly.
