Wireless charging alert dialog/Smooth Progress Bar 0.40.0

 - Reason for adding this most devices with wireless charging the oem
   software providers a popup when charging starts (eg. placed on
   charging pad) and when charging stops (eg. lifted off). I personally
   like this feature so thats what this does.

* Set on wireless charger and alert dialog pops up "Wireless charging"
* Lifted off wireless charger and alert dialog pops up "Charging stopped
* All this follows certain other settings too. Like Wake when plugged
  or uplugged. When wakeWhenPluggedUnplugged is true. Alert dialog
  happens as the device will wake anyway then. When false no alert
  dialog is done even.
