Pass options to initialization when adding a bucket

[johnkferguson]

Currently, running the command octopress deploy add-bucket generates the following error:

/octopress-deploy-1.0.0.rc.9/lib/octopress-deploy/s3.rb:8:in `initialize': wrong number of arguments (0 for 1) (ArgumentError)

This is because the deployment options used for setting up an S3 bucket are not passed on to the S3's class initialization method.

This PR adds the options hash as the arguments to the initialization call to S3.

Users should now be able to add buckets when setting up deployment.
