Added wxSimplebook class: a wxBookCtrl without controller.

This new control allows the program to show one of the several pages without
allowing the user to change them (or even see that there are several of them)
himself.

This class is fully inline, so it doesn't add anything to the library and
hence doesn't need neither wxUSE_SIMPLEBOOK nor the corresponding configure
option.
