Partly fix lockscreen blur rotation issue

This works very well when changing rotation from portrait to landscape and vice versa but doesn't work when changing rotation from landscape to landscape (90 to 270 deg) or portrait to portrait (0 to 180 deg) because we don't get notified of such changes.

Lockscreen Notifications [1/2]

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.
