_quantity() relationship modifications

There is no _num_quantity in the default relex, or, at least, there is not supposed to be, but I'm looking at the algs file, and it seems like it  slipped in by accedent. It was supposed to only be used as a device for alter how the stanford compatibility m,ode worked, and I'm guessing someone mist-understood and added that, and I failed to notice the change.

In fact, the entire rule NUMBER-NUMERIC-QUANTIFIERS looks incorrect ... I'm having trouble understanding what its doing.   Argh.   Its probably safe to remove it entirely.  We should have had far more extensive unit tests much much earlier.

Anyway, ... Hmm  _quantity(mile, more) seems wrong to me.  More on that in next post.
