Summary: We constantly have random bugs pop up when mutations are made outside of a batch update. This change restricts the mutation API to a batch context object (which is just an `IGListAdapter`) so they can only be done **inside an update block**. - Fixed open source project - Confirmed open source examples build - Updated all of Instagram.app to use this API - Changelog breaking changes entry Fixes #392 Reviewed By: jessesquires Differential Revision: D4754129 fbshipit-source-id: 11d32a0fac3e50c9edbb01e92a8a0c7b8a43cf2d
