TinyMCE:
- Update the 'paste' plugin including https://github.com/tinymce/tinymce/commit/cb36a78e544132ff58e96c4df168094b1a9960b1
- Better filtering of WebKit inserted &nbsp.
- Remove empty paragraphs and all inline styles on pasting but preserve styles added in the editor. This brings back the WP 3.8 behavior and makes pasting in all browsers work the same.

Move ms-load.php and ms-default-constants.php inclusion back to ms-settings.php to avoid breaking WP-CLI.

Use require_once() to allow for ms-settings.php to be included multiple times while testing.
