fix to make it work on WP 3.8

did not work after install:
– no <!–nextpage–> code was added to post
– strange “wp-table-of-paginated-contents//images/trans.gif” image was added before the proper [shortcode]

it sort of worked by adding a proper page break right before the [shortcode], but then wptopc and wptopc_pagination_links started using “Page X” rather than the title in shortcodes.

after looking for the file that output the gif, i modified wp-table-of-paginated-contents-tinyMCE-plugin.js at line 14:

ed.execCommand('mceInsertContent', 0, '<img src="' + url + '/images/trans.gif" class="mceWPnextpage mceItemNoResize" title="'+ed.getLang('wordpress.wp_page_alt')+'" />');
ed.execCommand('mceInsertContent', false, "[section_title title="+section_title+"]");

into:

//ed.execCommand('mceInsertContent', 0, '<img src="' + url + '/images/trans.gif" class="mceWPnextpage mceItemNoResize" title="'+ed.getLang('wordpress.wp_page_alt')+'" />');
ed.execCommand('mceInsertContent', false, "<!--nextpage-->");
ed.execCommand('mceInsertContent', false, "[section_title title="+section_title+"]");

that seems to be working, now i get:
<!–nextpage –>
[shortcode]
