Unit Type Labels
Added some additional Unit Type labels for products. "Each" is a very general term that can be applied to different ways a product is sold. For example, you may now select "Kit" instead of "Each" when creating a kit. And on the website it will list show the price "per kit."
Added a feature that allows for a store to add school districts and schools in settings. These school districts and schools will be used to populate RTO/RTR contracts in the till and on the website. This feature is only for the adding of school districts and schools in settings.
