[Cryptography Team] some more repository things

[Hans-Martin Mosner]

Hi folks,
I noticed that the package cutting 'Cryptography' and 
'Cryptography-SHA256' does not work well with Monticello, since MC works 
with prefixes to decide which classes and methods belong into which 
package.
Just had a chat with Cees on the IRC, and asked him about this. He said 
that this is a no-no and we should rather have packages 'Cryptography-*' 
for all our stuff, so that no single package name is a prefix of another.
This also means that extension protocols must be renamed.
Who can do this, and when? I can't do it this weekend, and probably not 
next week either, so someone else should probably go for it.

Cheers,
Hans-Martin
