Release Name: 0.8.1

Notes:
1. Operation#query_parameters was faulty, because it had accidentally been defined outside the Operation class.

   This meant that it wasn't in the correct namespace, causing libraries that included Ruby/AWS to place that method in a namespace unreachable by Ruby/AWS itself. Scripts that used Ruby/AWS without defining other modules and classes were unaffected.

2. In determining the home directory location of the .amazonrc file, we were mistakenly concatenating ENV['HOMEDRIVE'] + ENV['HOMEPATH'] without first checking that both were defined.

3. The version of the AWS API used is now 2009-11-01, the latest at the time of writing.
