Added soft wrap option to editor (attempt 2 after killing master)

Previously !6188 (merged).

What does this MR do?

Adds a Soft wrap button to the editor, when clicked, it wraps the text in the editor and changes to No wrap, then when clicked, it unwraps the text in the editor.

Are there points in the code the reviewer needs to double check?

Let's make sure we dont blow up master this time. 😨 😆

Why was this MR needed?
