Adds a Developer Error when attempting to add records without ids to relationships.
Removes the jQuery ready hold in SC.platform that was used to delay launching of the app until the transition and animation event names tests completed. Several browsers will not run the transition/animations in hidden tabs, which slows and possibly blocks an app from launching. Since the results of these tests are used only to optimize the event listeners set up in SC.RootResponder, the code has been changed to setup the root responder at whatever point the tests successfully finish. Closes #1120
Removes a duplicate listener on ‘selectstart’ events. It is handled separately in the code below.
Fixes regression in collection views so that they properly re-render when inside nested scroll views.
