More ramification theory

To me this is almost as bad as henselization; probably means that
there is a lot of room for improvement in the writing of this
material.

Neurotic changes

Given a finite extension L/K of the fraction field of a discrete
valuation ring, we say L/K is 'unramified wrt A' instead of just saying
that it is 'unramified'. There are two reasons:

  1. There may be more than one dvr whose fraction field is K
  2. We already have a notion of an unramified ring map and we do not
  want the reader to think we are asking K ---> L to be unramified as a
  ring map...

Yes, this is probably not necessary...

Level lowering in Epp's proof

The most intricate part is now done. Tried to make the mized
characteristic part of the proof resemble the characteristic p
part of the proof. It is clear that it works, but it is kind of
annoying to write down.

First version of second part Epp's proof (char p case)

Additional material for section on Epp's paper

Some of this material is wrong, will be changed etc.
