Revert "Swaps out @jlaxson's SC.SegmentedView#shouldAutoResize for @publickeating's suggestion that the behavior be mediated by setting shouldHandleOverflow to NO. (There is currently no way to prevent resizing in a static-width segmented view with shouldHandleOverflow: NO; if that's a need, it shouldn't be hard to implement.)"

This reverts commit 3f9128971e9ce7da0b97221a3dbd71975a90fb7c.
