Peek wake timeout (2/2)

- Originaly taken from AICP - Thath's why i'm keeping original autorship
- Allow user to set how long peek notification will hold screen on
- Minor changes by me @cristianomatos to match crDroid sources

Diff from original commit:
* Pass predefined values and made it as a list preference instead of seekbar
* Ensure summary and default value in clean installations
* Made multi user
