Animato: Added base-code for converting the ugly old bitflag settings

Only object layers have been done for now. The implementation of this should provide a good indicator for how this should be done. Unforunately, the code for animating layer visibility is not that straightforward, since scene->base->layer (not set) settings need to be synchronised with the object->layer (set by Animato) settings.
