Implement database ethercrafts to retroactively update highcharts series instead of using constants

@houndci 

I'll be further removing magic numbers to make a fully active-record dependent highcharts item for the test app for the next few branches (countries, numbers, characters, etc.)
Might want to make a variable in your controller that = Ethercraft.all, then use that here, instead of doing the database call in the view.
