Install the new version of CKEditor 4.5.3

Update our custom config file to add a few more toolbar buttons,
including 'source', which may be contentious.

This update also switches our theme and removes some plugins, such
as the "current DOM element" bar

The upgrade process looks like this:

[Update the copy of ckeditor in third-party. To do so, look at build-config.js]

$ cd share/web/static/RichText
$ rm -rf *
$ cp -a ../../../devel/third-party/ckeditor/* .
$ rm -rf README.md LICENSE.md samples/ build-config.js CHANGES.md
$ echo  "\n\n// RT override:\nbody { background-color: transparent;}\n\n" >> contents.css
$ git co config.js

[ Update config.js to add new plugins or massage toolbar ]

$ git add .
$ git commit
