Fixes related to using variable width UICollectionView cells

    - reset transform on menuViewController after the view disappears.
      This allows for looking up the frame value on the subviews to adjust
      for appropraite cell width while reloading layout.

    - during rotation handler allow view/didViewAppear callbacks so layout
      can be adjusted appropriately before rotation happens.
