checkincludedtext behavior

[Jeffrey M. Vinocur]

We have a feature request to make the cutoff length below which
checkincludedtext in inn.conf does not apply (currently 20 lines; was 40
lines in the past) customizable.

I suppose the thing to do is to pull it into inn.conf and additionally
make it overridable in readers.conf (just like checkincludedtext).  Maybe 
make the ratio between new and included customizable as well?

Or do we want to declare that anybody who wants to fiddle with this should
just disable it and use a posting filter?
