Rubber 3.2.1 Released

[Kevin Menard]

Hi all,

I'm pleased to announce the 3.2.1 release of Rubber. The big change here
is a regression fix for EC2 Classic support that accidentally broke with
the introduction of VPC support in 3.2.0. Thanks to Dave Benvenuti for a
quick fix. The remaining items were courtesy of Johnny Shields.
