- navring has targets for handling vib/mute/sound
- added Color class based on blk_jacks idea which first grey an icon out
  and then color it. This gives way better results. As well it fits now
  perfectly with the new 4.4 UI. Put it on a central place so that it is
  from everywhere available. notification shortcuts adapted to the new
class
  place
- complete new icons thanks to kroz who has redone all for xxhdpi
- our slim special swipe drag drop press longpress options support
  like on 4.3 this two features
- a lot lot fixes as well on current google code
