eb28eaf320 Update taler.tex to refresh protocol with new coin derivation 
I made usages of the FDH explicit too, but did not realyl explain it.

cdcd67a27d Use KDF better 
We now send the secret_seed to the skm variable, while sending the
counter salt to the xts variable.  I have not check this with
http://eprint.iacr.org/2010/264 but it seems correct.

Indeed rsa_blinding_key_derive places the strong source of
randomness in skm too, and uses a constant string for xts.
