[1/2] FW: LockScreen Notifications by AOSPAL

THANKS AOSPAL -> David L.-W <david.leppla.weber@gmail.com>

Port from: http://review.carbon-rom.com/#/c/1399/

My try on making notifications easily accessable from lockscreen.
Credits to ChameleonOS, I got the notification listener permission and some small other stuff from their ActiveDisplay implementation.

Lockscreen Notifications allow you to manage all your notifications directly on the lockscreen.

Features:
- Pocket mode turn screen on when phone is pulled out of pocket and turn it off when phone gets back in pocket
- Hide low priority notifications
- Hide non-clearable notifications
- Allow dismissing even non-clearable notifications from lockscreen
- Just turn screen on when there's currently a notification pending
- Toggle between expanded and normal notification view by longpressing

This should still be considered as beta, even if it seems to work very well for me.

Lockscreen Notifications: Make "wake on notifications" user configurable

and some other small changes that hopefully will improve battery live

Lockscreen Notifications: fix possible NPE

Lockscreen Notifications: try on fixing notifications sometimes not responding

Lockscreen Notifications: always scroll to bottom so one sees the newest notification first

Lockscreen Notificaitons: Fix NPE while on setup wizard on clean flash

Lockscreen Notifications: several fixes

- fix notification not responding when removed and added in a short period of time (e.g. gravity screen start/stop)
- just unlock screen on notification click when there's an activity to start
- fix notification hide animation
- just wake screen on reposted notifications when it's not ongoing (wake on notification before made the device stay awake for ever when a download/countdown or something similiar was running)
