Title: Support only_process option to process_in_background

Paperclip::Attachment.reprocess! doesn't use the only_process option set by `has_attached_file`.

By default, reprocess! will delete and rewrite every style, including `:original`, which is unnecessary if you're just creating thumbnails.

Includes passing test & readme update.
