Add 4Play & SNES MAX card support (#946, #972, PR #982)

Support these new cards in slots 3, 4 or 5; based on code from Lukazi. - extend Configuration's Input prop sheet page. - add save/load snapshot for both cards. - add command line switch for alt controller type (for SNES MAX card). Change to using Registry's 'Configuration\Slot 3' for slot 3 cards (Uthernet, 4Play & SNES MAX). Update help doc.
