Steam Library 'What's New' Yeeter script

What's this?
    This batch/powershell script hides that annoying "What's New" shelf or section from your Steam Library

Use instructions:
    - Navigate to your Steam install directory (usually "C:\Program Files (x86)\Steam")
    - Go into "steamui\css"
    - Drop both BAT and PS1 files in the "css" folder (it should be in the same folder as "chunk~2dcc5aaf7.css")
    - Double-click the BAT file
    - Repeat the previous step whenever "What's New" pops back again into your library
    
    You may want to create a shortcut to the BAT file for easier access in the future
