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`

Apply the case-insensitive network-site comparisons added in [27725] for `wp-admin/network/admin.php` to `wp-admin/user/admin.php` too, for consistency.

`wp-admin/network/admin.php` is required by all of the individual network templates and begins with an `is_multisite()` check of its own. Because of this, we can remove the 26 other checks in the individual templates.

* All WordPress files move to a src/ directory.
* New task runner (Grunt), configured to copy a built WordPress to build/.
* svn:ignore and .gitignore for Gruntfile.js, wp-config.php, and node.js.
* Remove Akismet external from develop.svn. Still exists in core.svn.
