Add data-cfasync="false" to script tags

[jblz]

Description

The current version of the plugin adds a data-cfasync="false" attribute pair to the script tags:

wp-parsely/parsely-javascript.php

Lines 22 to 24 in de02bbd

	<script data-cfasync="false">
	function uuidProfileCall() {

wp-parsely/parsely-javascript.php

Line 57 in de02bbd

<script data-cfasync="false" id="parsely-cfg" data-parsely-site="<?php echo esc_attr( $parsely_options['apikey'] ); ?>" src="//cdn.parsely.com/keys/<?php echo esc_attr( $parsely_options['apikey'] ); ?>/p.js"></script>

wp-parsely/class-parsely-recommended-widget.php

Line 67 in de02bbd

<script data-cfasync="false">

This change:

• Adds the API script to the list of handles that gets the treatment
• Fixes the preg_replace to actually work
• (minor) changes a short array syntax to long to match existing code style

Motivation and Context

It was intended to replicate this behavior in #236, but it did not make it into the change.

I didn't find a whole lot of context around the need for this, but there's #129. @hbbtstar -- can you please take a look and let me know if this is the right approach?

Some more context: this attribute looks like it's used to have Cloudflare's Rocket Loader "ignore specific JavaScripts."

How Has This Been Tested?

• Automated tests added to confirm the attribute is correctly printed in this branch
• Source inspected to do the same

Screenshots (if appropriate):

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

As a side note, I would like to find a way to make these optional - that is, to have a filter that can conditionally add these integrations in, since they are redundant for the majority of sites that are not behind Cloudflare.

Agreed. Tracked in #293
