 Steam Library 'What's New' Yeeter script

What's this?
	This batch/powershell script hides that annoying "What's New" shelf from your Steam Library (on Windows)

Use instructions:
	- Navigate to your Steam install directory (usually "C:\Program Files (x86)\Steam")
	- Go into "steamui\css"
	- Drop both BAT and PS1 files inside this "css" folder (the files should be in the same folder as the file specified in "$targetfilename")
	- 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
