OBS for Game Clients

	The purpose of these modifications to OBS are to provide an easy way for game clients 
	to utilize OBS's rich streaming featureset while being mostly a background process, 
	transparent to the user of the game.
	
	- Command line arguments have been added to start OBS with settings from the game.
	- OBS can be 'attached' to the game client. 
	  If the game client closes for any reason, OBS can shutdown.
	- Option to hide the main window, but retain system tray icon 
	  with minimal functionality.
	
	These changes have only been tested on Windows, but may work on other platforms.
