Add XRC handler for wxSimplebook.

Similar to wxNotebook but even simpler as wxSimplebook doesn't use images.

Also add wxSimplebook::Create() as the version inherited from wxBookCtrlBase
didn't _quite_ work: we need to add wxBK_TOP style to prevent asserts due to
unknown alignment in the base class when creating wxSimplebook.
