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.
