Bread-Baking update.

This is the code. I am not sure that it will work at all, but it is at least a try.

It's a good start, but there are some loose ends that need to be tidied up before merging the pull
I can merge and then clean it up when I have time, or you can take a look at it yourself.
Making all of your names and modes capitalizes violates the style of the original data set and makes consistent integration and updating much more difficult when some things are capitalized and some things are not. For example, the default data.js actually has a resource item called 'bread' which already has an icon, but it's not actually used in the game. You could easily refer to that instead of defining a new 'Bread' resource.
Making grain and flour part of food means that they are getting eaten raw instead of being turned into bread. You can put them in the food category for display but not "partof:food" to treat them as just an ingredient.
The settings button doesn't do anything if you don't add it as a requirement for the technologies and the modes (add "'enablebread':'on' to the req list for the various elements), and you will want to use my convertUnitMode function to change modes on any existing units (eg if you have 5 artisans grinding when you turn the option off, you need to change their mode to something else otherwise they will keep going with a mode that shouldn't even be available).
Similarly, I would move the addition of grain gathering to the callback function when the setting is turned on, and delete the gathering mode when turning the setting off. The idea is, if the setting is disabled, then the game should look and play exactly like it did if the mod were not even there.

If I have time, I'll look at making these changes and testing before merging into the master. Thanks for contributing!

You might want to add a policy to disable eating raw grain since it tastes so bad.
