finish up state indicator in new legend
remember settings when lines are toggled on/off
uses localStorage and defaults to all lines being visible
Fixed issue 30, thanks zoik/peteoc for finding it
Merge branch 'develop' into feature/new-beer-chart-legend
fix the bug where "idle" state was being ignored
change state indicator to a solid square
forego use of "--" with text "State" this matches Date/Time handling a bit more
