Title: add query options for s3 to support response headers overwriting

As title says this commit lets you add query params to s3 urls, so you can override response headers.

Example:
my_uploader.url
my_uploader.url(:thumb)
my_uploader.url(:thumb, :small)
my_uploader.url(:query => {"response-content-disposition" => "attachment"})
my_uploader.url(:thumb, :small, :query => {"response-content-disposition" => "attachment"})
