Enhancement: Support multiple static domains for increased performance

[CaMer0n]

Usage:

Create several subdomains with cdn1, cdn2, cdn3 etc for your domain, making sure that each of them point to the public_html folder. ie. When entered into the browser, each domain should appear identical to each other.

eg. Add the following to your e107_config.php file: (replacing each domain with the ones you just created)

$domains = array('http://cdn1.test.com/', 'http://cdn2.test.com/', 'http://cdn3.test.com/e107v2/');
define('e_HTTP_STATIC', $domains);

Visit your main domain. If you check the source-code, you should find that your css, js and image files are loaded from each of these sub domains.

• Requires PHP 5.6 or higher to use an array. Earlier PHP versions can use one value only: define('e_HTTP_STATIC', 'http://cdn1.test.com/');

[Serios]

I tested this on PHP 5.6.29 and unfortunately it doesn't work with arrays, it throws "Constants may only evaluate to scalar values" error.

However if you define e_HTTP_STATIC like this: const e_HTTP_STATIC = ['http://cdn1.test.com/', 'http://cdn2.test.com/', 'http://cdn3.test.com/e107v2/'];

It's working properly
