Niels Sascha Reedijk 5cfca119fb HaikuBook: Add documentation for BCardLayout
This adds documentation for BCardView, BCardLayout and BLayoutBuilder::Cards.
There is also a bit of cleanup for the BSplitView documentation.

It also makes explicit when a developer passes an invalid argument to
BCardLayout::SetVisibleItem(), by making that a debugger() call.

\brief BLayoutBuilder::Base subclass for building BCardLayouts.
\since Haiku R1
The BCardLayout class is a simple BLayout subclass that arranges the
items as a stack of cards with only one card being on top and visible to
the user.
For a detailed view on the properties, see the \link BCardLayout class
