Remove old ckeditor
Update ckeditor to 4.3 full version
Precompile ckeditor images
Update rake task to create non digest assets

The original rake task did not work for me. The output was:
```
"Copy /tmp/build_0d494270-5e35-4650-85b6-f25d45c5e2b0/vendor/bundle/ruby/2.0.0/bundler/gems/ckeditor-6ac7f1eb21cb/vendor/assets/javascripts/ckeditor/contents.css to /tmp/build_0d494270-5e35-4650-85b6-f25d45c5e2b0/public/assets/ckeditor/contents.css"
```

Now it seems to work: 
```
cp public/assets/ckeditor/skins/moono/icons_hidpi-37c74fe2d448f1f89bae6e815940580e.png public/assets/ckeditor/skins/moono/icons_hidpi.png
```

The code is based on https://github.com/bastiaanterhorst/rich/blob/master/lib/tasks/rich_tasks.rake

This reverts commit 1cc9474765678fc52911949c8e0a95ef3e59c53c.

If we encapsulate identification with ckeditor_current_user, why use again current_user?

remove host from resource url

this allows the use of asset_host and ckeditor and still works without asset_host set as the /assets is a valid relative path

Unescape Javascript code no matter what

Rails 4.1 has better JSON encoder. Everything boils down to JSON literals and
all strings are escaped. The JavascriptCode class too boiled down to an escaped
string.

Here we just gsub the quotes out.
