Saves and populates form elements from local storage

	/*

	Just put a "data-storage-key" attribute on your form fields:

	<input name="authkey" data-storage-key="saved_auth_key"/>

	The value can be anything that is a valid key in localStorage (stick with mostly strings and you'll be fine).

	When the form submits, whatever is in the field will be saved to local storage under the provided key name.
	Next time the page loads, that form field will be populated from local storage.
