* Move replacement tests from test/unit/upload_service_test.rb to test/functional/post_replacement_controller_test.rb * Move UploadService::Replacer to PostReplacementProcessor. * Fix a minor bug where if you used the API to replace a post with a file, the replacement would fail unless you passed an empty string for the replacement_url.
