Many changes for wxInputHandler creation mainly related to:

1. Allow the theme to create only the input handlers it customizes instead
   of forcing it to always create a handler even if the standard one is used:
   wxTheme::GetInputHandler() now takes wxInputConsumer to make this possible

2. Prefer delegation to inheritance when creating customized input handlers,
   almost all (except for wxStdScrollbarInputHandler) standard handler classes
   are now private, use wxClassName::GetStdInputHandler() to retrieve the
   standard handler for any class or polymorphic DoGetStdInputHandler()
