android notification service stub, improve login

Added retroshare-android-notify-service a stub will handle notifications
  to android system, at the moment it only attempt autologin if default
  password is used
retroshare-android-service quit QCoreApplication gracefully
Android Studio update has changed some android build files
Create BusyOverlay.qml componet so it is reusable accross the qml app
Contacts.qml create a pseudonimous GXS identity as needed without
  prompting the user
RsLoginPassView.qml nicer look, on mobile phone password usage is not
  common so do not use password by default
QML app main view handle correctly +waiting_startup+ runstate
QML app main view use BusyOverlay as initial item
