Added soft wrap option to editor

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.

This will also detect files with no extension, .txt or .md and proactively set the soft wrap. Unless, you explicitly toggle the soft wrap, then it will stop checking the file path and will stay with the users explicit preference.

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

We should talk about the .txt and .md thing, I'm not sure if its a good approach.
