CKEditorConfig - Fix double-escaped slashes

[colemanw]

Overview

The "Advanced Options" section of the CKEditor configurator allows user-input strings. Slashes were being escaped multiple times in that input. This fixes it.

To reproduce the bug:

• Add an advanced option and enter a string containing slashes.
• Click "Save"
• Observe on reloading the form the string has changed, adding extra escaping slashes that should not be there.

Discussed this with Tim and we feel there isn't any potential issues that might be generated from the non escaping of / Merging
