This fixes the section edit highlighting when the start marker (normally
a heading) is inside other HTML elements like a div from the wrap
plugin.

This adds more tolerance to the width calculations of the media manager
panes which avoids that the right pane is displayed below the other
panes.

Instead of a dedicated function to toggle the TOC we now have a function
that allows to use this functionality everywhere. This will be used to
toggle the sidebar in the mobile view (in an upcoming patch).

Note, this required some changes to the CSS (to make it more generic).
The CSS is still located in the TOC sections but should probably be
moved into its own section instead.

Attention: Template authors need to adjust their CSS!

Original structure:
div.toc >
  div#toc__header.tocheader.toctoggle > span#toc__toggle.toc_close|toc_open > span
  div#toc__inside > ul.toc > li.level1 > div.li > span.li > a.toc

New structure:
div#dw__toc.open|close >
  h3 > strong > span
  ul.toc > li.toc > div.li > a

server-side on uploading.

A trailing comma created an empty array item causing IE8 to choke.
