Settings: : Slim heads up customizations for LP (2/2)
Basically it follows the same idea like we had on SlimKat....see here
SlimRoms/frameworks_base@323ed77

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.
Settings: add headsup manifest permission

Settings: make unaccounted and over-counted battery usage configurable
Google disabled it for release builds here:

e679377

well but it is enabled for whatever other type of builds beside the official release builds. That said it should
be a developer option so or so and not build type dependent.

Whatever added an option into developer settings to control it. Default value is false.

That said.....finally no complain about misc battery stat in battery settings xD
