Frameworks: Slim heads up customizations for LP (1/2)

Basically it follows the same idea like we had on SlimKat....see here
https://github.com/SlimRoms/frameworks_base/commit/323ed77c5e5bd6d421beae1f8118eb580be5ecf1

That said there are some differences in this more or less completely recoded feature.

- Moved it into the app policy files
- Enable/Disable on every app (no system apps)  either longpress a notification and an button appears / or in notification app settings
- For now only snooze and heads up timeout configurable....other stuff will follow later.
- fix up some AOSP code for it as well fix some UX inconsitence.
- left swipe dismiss, right swipe put into background, swipe down opens notification drawer and moves the notification into it
  (aosp default behaviour is a big UX disaster....swipe up dismisses it completely and swipe down open notification drawer but heads up stays....first
   happened to me 10000 times accidentally which is really bad and second does not make sense. Hence this change of the default behaviour)

Well and a lot smaller things as usual.

Last PS
- fixed some minor stuff
- reset snooze timer when screen goes off
- do not show headups if notification drawer is visible

PS
making snooze button functional - we may need to move it a bit down.

PS
give snooze button a bit animation love

PS
icons

PS
add accessibility descriptions etc

SystemUI: improve brightness slider behavior

Mimic the brightness slider behavior in the statusbar.
This adds logic to make the statusbar slider also work with automatic
brightness mode enabled and it will instead adjust the temporary automatic
brightness overrride.

Update color dependent items when reusing notifications.

The notification might have changed its color setting.

Frameworks: Only set package name on user heads ups

Let us not influence the default aosp behaviour which could conflict if an app
is strange coded
