Multisite: Introduce the WP_Network class.

Browse Source 
A `WP_Network` object initially matches a row from `wp_site` and is populated with additional properties used by WordPress core. The first iteration is used to retrieve an existing network based on data passed to the class.

* A network can be retrieved by its ID through `WP_Network::get_instance()`, following in the steps of `WP_Post` and `WP_Comment`.
* A network object can be created or completed by passing initial properties in as a standard object to `new WP_Network()`.

Using these methods, we are now able to populate the global `$current_site` during load via this class.
