8667	Revive model inheritance documentation	Malcolm Tredinnick	nobody	So I don't forget: the model inheritance documentation seems to have been dropped during the docs merge. So we have to extract that out of the old models-api.txt. There was quite a bit of it, mostly all in one block towards the end of the file. Plus a couple of references earlier (e.g. in the related name section).		closed	Documentation	dev		duplicate			Unreviewed	0	0	0	0	0	0
