Cryptix 3.0.3

[Bill Frantz]

I have spent the afternoon (between many interruptions) looking at Cryptix
3.0.3.  It looks like the Cryptix 2.2 compatibility mode will work with
OpenE with no changes to OpenE.  The only problem is the install mess.  :-(

For the future, the Cryptix IJCE (International Java Cryptographic
Extension) interface allows us to do things we can't do with Sun's JCE.
Specifically, find out what crypto algorithms are available.  My suggestion
for the next step for OpenE crypto is to set up the startup protocol so it
finds out what algorithms are available and then offers them to the other
end as part of the negotiation.

This change will get us mostly out of having to decide which algorithms to
use.  (We still need to figure out a preference order for algorithms so we
don't use DES in favor of 3DES for example.)
