More Brightness Adjustments

- Remove 5-10 and 10-50 ranges because this seemed to trip a lot of
  brightness changes in dim lighting now that the PowerManager can
  adjusts the brightness without requiring a suspend/resume.

- Replace those with a 5-100 range that is set to 25. Keep the 0-5
  range for late night book reading though.
