PEEK [1/2]
Sensors are fully disabled when screen is on. When you turn the screen off,
it will start polling both gyroscope and proximity sensor values. If it detects
using the gyroscope sensor that device is lying on a table, it disables proximity
polling. If it detects with proximity sensor that it is in your pocket, it disables
gyroscope polling. This way, we save some battery from the beginning. Later, when you
receive a notification, it enables a partial wakelock (CPU on but at low frequency),
and starts listening for movement, either from getting it out your pocket or lifting
off from the table. If it detects those events, it will turn on screen and show the notification.
Wakelock timeouts on 10 secs, so if you receive a notification and there is no movement in that time,
sensors will stop polling after that time, disabling peek interaction until a new notification comes.
Peek doesn't process low and min priority notifications.

PEEK: Beautify bridging layers code

* Save new instances for Peek and PowerManager:
    Create it only in BaseStatusBar when start() method is called. That one
    will be passed throught the sub layers such like new helper class so another
    feature can check Peek state invocking from NotificationHelper class.
* Move phone listener to new helper class.
* Do not show Peek on sim pin lock screen.
* Process new incoming notifications only if screen is off, keep updating notification array separately.
* General cleanup.

Keep app when opening floating window from recents panel

Start activity asynchronously by appending it to system's
message queue to let RecentsPanelView cleanly execute
dismissAndGoBack before the floating window gets started.

HOVER: Don't treat touch outside event as true if is animating

- It needs to wait animation to be finished to start listen for touch outside
  and runs hide timer.

HOVER: Respect screen limits when adding view

As for what @Decad3nce reported here http://review.cyanogenmod.org/#/c/66654/
we shouldn't keep FLAG_LAYOUT_NO_LIMITS so view doesn't exceed the screen limits.

Thank you Adnan :)
