Try to use L/K notation for field extensions

We could also try to consistenly use "field extension" and not just
"extension" and consistently use "ring extension", etc.

Fix mistake in more-algebra

Not a fatal mistake by any means and not bad at all, but annoying to
fix. Namely, it seems that we need to use the following when we prove
that our property is inherited by henselization or strict
henselization: given

k ---> k' ---> R

where the first arrow is a separable algebraic extension of fields and
where k ---> R has property P, then k' ---> R has property P as well.
Now if k'/k is finite, then this follows from (A) and (B). But in the
case of an infinite extension it does not seem to formally follow from
(A) and (B). Thus we added it as a new property and we checked this
property in all of the cases...

Improve exposition of P morphisms

Add section on properties of formal fibres

Lists properties (A), (B), (C), (D) of a property of Noetherian
algebras over fields which are a kind of minimal requirement for
the thing to make sense.
