Summary: Adds Reference List as a widget type. Reference List is similar to Choice List: multiple references can be added to each cell through a similar editor, and the individual references will always reflect their current value from the referenced table. Test Plan: Browser tests. Reviewers: dsagal Reviewed By: dsagal Subscribers: paulfitz, jarek, alexmojaki, dsagal Differential Revision: https://phab.getgrist.com/D2959
