Gesture Anywhere: Add gesture anywhere feature into the ChaOS Lab [1/2]

When enabled a user can activate the gesture anywhere view by touching
the designated trigger area.  If a gesture is recognized as one the user
has created and assigned to an action, that action will be performed.
Since this is part of the system UI and implemented as an overlay, it
will be available and usable system wide, with the exception of the
keyguard for obvious reasons.

Delay hiding systemui by 100ms
When disabling the keyguard, the systemui visibility is
changed and can occur after we hide it so delaying this
a bit resolves that issue.

Active display: Enable proximity sensor only when screen is off

This should ease people worried about cpu usage of the proximity
sensor while the screen is on.  The sensor listener will only be
registered when the screen goes off, and both active display and
pocket mode are enabled.  Once the screen turns on this listener
will be unregistered so no further updates are received when the
sensor values change.

Active display: Use a default notificaiton icon.

In case there is an exception when trying to load the
notification icon we will use a default one.

Active display: Only fetch next notification if mNotification is null.

Active display: Don't show active display if call state is not idle.

This will prevent active display from displaying when a call is
coming in and let the call screen show up instead of active display.
