This commit adds a generic interface for cell types and hooks it up. There is no way to set these from the UI, and so they're not saved anywhere yet. Also implicitly converts numeric values (strictly integers) to numeric javascript values, as numbery-looking + numbery-looking === string is not very interesting. :^)
