Many suggestions of improvement

I need your help, I think I found a bug. I wondered why my encodings crashed.

When x264 preset is set on "superfast" on the encoding line, and you add p8x8 or b8x8 partitions, instead of adding the "--partitions" argument to add these values, Hybrid will stick these values with another arguments, randomly, just like that :


Which make encoding crash, obviously.
