Merge branch 'add-info-stats-page' of git://github.com/dirkhh/subsurface

* 'add-info-stats-page' of git://github.com/dirkhh/subsurface:
  Add Info & Stats page to the notebook
  Even more places with pressure and volume conversions
  Further cleanup of pressure and volume conversions
  Use unit functions to get column headers, add unit function for pressure
  More consistency improvements
  Add new helper function to get temperature and unit
