Add TinyMCE PDW Toggle Toolbars plugin to whitelist

Same question as in #1509850: Add MarkItUp library to Whitelist. Could this just be handled with a patch? e.g.

libraries[ckeditor][patch][] = "http://drupal.org/files/1337004-ckeditor-remove-samples-3.patch"

Repurposing this issue for the PDW and Spellcheck libraries, which are currently sitting in https://github.com/populist/panopoly_wysiwyg.

Here are the relevant TinyMCE plugins (I think):

http://www.neele.name/pdw_toggle_toolbars/
http://www.tinymce.com/wiki.php/Plugin:spellchecker
http://www.tinymce.com/wiki.php/Plugin:inlinepopups

Unfortunately, I can't find any license information for any of these. I'm not sure if it's safe to assume they inherit the same license as TinyMCE (http://www.tinymce.com/wiki.php/License - GPL 2.1) just as Drupal does, but possibly.

spellchecker and inlinepopups are both internal TinyMCE plugins, which are not separate libraries in the first place.

I think it's safe to assume that PDW uses the same license as TinyMCE (GPL and LGPL).

Ok, if that's the case, the whitelist entry looks like:

^http://www\.neele\.name/pdw_toggle_toolbars/download/pdw_toggle_toolbars_.+$

I'll leave this for a day or so and see if anyone on the team objects.

No complaints here.
