Improved sleep chart #45

- use just one data set, because multiple data sets is not supported
  by MPAndroidChart (the way we need it)

Now there is hardly any space between the bars anymore

Also:
- allow scaling x and y axis independently via pinch gesture
- set fixed y max value (1.0) so that the display is stable and
  independent of the actual available data
- (at least temporarily) display y labels
