New Custom Field Type - Hybrid Select String with Datasource Options

A hybrid between the select field type and the datasource field type. It would have a datasource to provide the options, but instead of storing an ID, it would store a String (name of datasourced item).

This would be convenient when many tables need to have common options, but for easier output on the front-end and easier sorting/searching it is more convenient to save that selection as a string than an ID (or array of strings for multi).

When using this, there would have to be an understanding that if an option is renamed, the old selection would remain selected in items.
