Fix 'const' declarations in non-strict mode are not supported
Fix 'const' declarations in non-strict mode are not supported

Without `'use strict';` I get lint errors of `'const' declarations in non-strict mode are not supported yet on Node 4.5.0` due to the new node linting rules. Adding this fixes the issue. Alternatively, we could disable that rule for this file or altogether.
