(Multi-Monitor)Better Handling

Browse source 
-Add back use of last_position_x and last_position_y
-last_position_x and last_position_y will be set to undefined when the window is shutdown IF the current display used is not the desired display
-last_display will be set to desired display at window shutdown if not the same
-vid_displayindex clamped using ClampDisplayIndexCvar() at startup and window shutdown
