Using `var` or only `static` to declare a class property is PHP 4 code.
This updates the codebase to use explicit visibility modifiers introduced in PHP 5.
Props jrf.

This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`

wp-tests-config.php can/should reside in the root of a develop checkout. `phpunit` should be run from the root.
