Hopefully fix new SteamLibrary

* Fix value between 0 and 1 being shown as percentage, this is now multiplied by 100
* If CS:GO is not found, it will also return from the function as not to execute the background worker causing an exception
* Using the new libraryfolders.vdf instead of the legacy config.vdf to fetch all libraryfolders. This is controllable via the new preprocessor directive NEWLIBRARYLOCATION
