* Adds script data to registered components.

* @note This method implements the ability to add additional inline data to specific scripts.
* As of v3.4, WordPress® is still lacking functions to interact w/ this feature.
* Therefore, we'll need to access `$wp_scripts` directly.
*
* @param string|array $components A string, or an array of specific components that need `$data` (i.e. inline JavaScript code).
*
* @param string $data The data (i.e. inline JavaScript code) that is needed by `$components`.
*
* @throws exception If invalid types are passed through arguments list.
