Merge pull request #265 from luxx/master

fix docs for maximum delay_seconds
Resolved an issue with errors with empty response bodies.

When the response body was the empty string, instead of nil, we would not properly map to helpful error types. This change fixes the empty string case.

Fixes #260
Fix indentation.
Removed incorrect documentation about SSE and Amazon S3.

Fixes #269
Reformatted client API documentation to fix rendered html for nested params.
Added a basic repl executable as aws-sdk-repl.

This repl will default to pry when available, but will
fall back to irb when not available.  It accepts a number
of runtime configuration options and defaults can be exported
to ENV.

By default client requests are logged (in color).  A quick
example:

    aws-sdk-repl
    AWS> s3.buckets['aws-sdk'].objects['key'].content_length
    [AWS S3 200 0.875184 0 retries] head_object(:bucket_name=>"aws-sdk",:key=>"key")
    => 5242881

You can use all methods of the AWS module directly when using Pry.
Corrected spelling error in comment.
Modified the repl include and require options.

* Now requiring the aws-sdk gem after the $LOAD_PATH
  has been amended.  This allows the user to point
  the repl to a different version of the SDK.

* Now requiring any files specified via -r. This happens
  after the SDK has been loaded and configured.  This
  alows the required library to make use of the SDK.
Changed the usage banner to match the (current) executable name.
Renamed the aws-sdk-repl to aws-rb.

* Renamed the script
* Updated the gem specification executables
* Renamed the ENV prefix from AWS_SDK_REPL to AWSRB
Resolved an issue with AWS::EC2::Instance#console_output

When the output xml element is missing from the response to
GetConsoleOutput then this method was raising an error.  This
now returns +nil+ indicating the output is not available.

Fixes #272
Added addition tests around loading the SDK.

Because the SDK uses autoload, it is necessary to run these
tests in separate processes.
Added a task to run each spec file in its own process.

Updated a few specs that were failing when run directly.
Moved the SNS client from sigv2 to sigv4.
Removed v2 specs from SNS client, now using v4 signer.
Bump version to 1.11.3
