[MOD] Trim whitespace between author name and comma

Script manager

KES version

4.3.0-beta.8

Describe the add-on

mbin inserts an extra whitespace between the username and comma when showing attribution for posts.

Instead of looking like:

Post Title
author, 5 days ago

it looks like:

author , 5 days ago

This would be a simple mod under the Fixes category to trim this extra whitespace.
