change each output separately

I noticed that autorandr doesn't work when I'm connecting 2 external displays. Autorandr then called xrandr --output LVDS1 --off --output HDMI1 ... --output VGA1 ....., and xrandr refused to operate on three outputs simultaenously (I suspenct that intel driver can "see" only two outputs in one time). 

So, I modified code to split options per output, execute "--off" options first, next "turn on" options next.
