public function LibrariesWebTest::_testLibrariesOutput in Libraries API 8.3

Tests that library files are properly added to the page output.

We check for JavaScript and CSS files directly in the DOM and add a list of included PHP files manually to the page output.

@todo Remove or rewrite to accomodate integration with core Libraries.
