From 72ddd7b7704f2087a52c9c0552446682918c513b Mon Sep 17 00:00:00 2001

Subject: Implement basic game files download logic

Implement core clap arguments

Respect XDG_BASE_DIR

Currently library extraction is broken because it assumes every instace has it's own library folder. This should be refactored so instances share libraries
