A little while ago, the 'base64' methods were sensibly moved into
their own module, Base64.

But that means one has to do this:

  plain = Base64.decode64(encoded)
  encoded = Base64.encode64(plain)

This would read better as

  plain = Base64.decode(encoded)
  encoded = Base64.encode(plain)

Can we have aliases, please?  In time for 1.8.2?  I'd submit a patch
but I don't have CVS access right now.

Cheers,
Gavin
