Auto trim trailing white space

To ensure trailing white space is trimmed do the following

Open VS User Settings (Preferences > Settings > User Settings tab). Click the {} icon in the top-right part of the window. This will open a document.

Add a new "files.trimTrailingWhitespace": true setting to the User Settings document if it's not already there. This is so you aren't editing the Default Setting directly, but instead adding to it.

Save the User Settings file.
