Long clicking on settings gear in QS causes it to accelarate and
spin, when released it will open and enable the tuner. On first
opening there will be a warning dialog.
Also add way to disable tuner from tuner screen. This way it can
be removed from its former home in Developer Settings. All tuner
settings are reset when disabled to match developer settings
behavior.

Also modified the shortcut key handling so that it drops chorded
Search+X keys when even if no shortcut was found. Without this
change, pressing an unhandled shortcut causes the Search widget to
pop up and the character to be typed.
