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.)
Just  a personal preference.... 
If you're planning on styling the rest of this view, I would suggest creating a stylesheet for the index view. That way you wont confuse yourself later where you'll have styling stemming from 2 different files for one view. This is just a nit pick, since it is just a dimention style.
