Settings: Change theme do Material (Dark), (3/3):

Changes to default Theme.Material:
- Use colorAccent from Theme.Material.Light,
  (For me the colorAccent from Theme.Material is to bright)

- Use a dark blue gray color for dashboard category background,
  preference- and dialog/picker backgrounds,
  (dashboard category background has to be black
  compared to Theme.Material.Light, for me it doesn`t looks good,
  also the preference- and dialog/picker backgrounds from
  Theme.Material are to bright in my opinion)

- Status bar and action bar is still Theme.Material.Settings,
  (I prefer these colors)
