CAST5 now works

[Werner Koch]

Hi,

just a short notice, to tell you all that finally I made
CAST5 encryption working and it should now be possible to
decrypt/encrypt PGP 5 messages (with PGP's CFB mode). The
code for the ciphers is now more structures and it will be
very easy to add new symmetric ciphers. I should do these
cleanups for the pubkey ciphers too. 

I have to write some new test cases and do some other cleanups
before the next release, but you have it before Friday.
