Hook_Manager now only manages hooks.
Renderer_Detector is used to detect the game's renderer. There will be 2 version of it. 1 for windows and 1 for Linux.
Some games doesn't initialise Steam before initalizing their Renderer (even if the doc says to) . So instead of waiting for the game to initialize it, hook to the rendering functions and deduce which implementation should be used.
