Small error in JavaScript file

In scripts.js, there’s a little error that is triggered in certain use cases. Right at the start you find this:

'use strict';

if (typeof _wpcf7 == 'undefined' || _wpcf7 === null) {
	_wpcf7 = {};
}

If _wpcf7 is indeed undefined, the strict mode will throw an error that _wpcf7 is undefined when trying to declare it. Simple fix: use var _wpcf7 = {};.

I haven’t check for other strict mode compatibility errors but it might be worth to run this through JSLint.

Cheers!
