Allow quickscrub after deadzone consumes touch

Moved deadzone detection to QuickScrubController so that quick scrub can
still occur. If anything is consumed by deadzone, no other touches will
occur however quickscrub can be detected and function with launcher. No
other events except for touch down will be sent to launcher.

Test: scrub right above the home button
