Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h` and makes each users include `mozilla/PresShell.h` instead. So, this improves rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the future). Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for `PresShell` in a lot of classes which are derived from `nsIFrame` even in `.cpp` files.

A frame that can have multiple children. Only one child may be displayed at

one time. So the can be flipped though like a Stack of cards.
