Add support for Keen IO
add better to test for identify for Keen, fix up some dot notation
use cloudfront.net domain for keen JS lib so it works over https
Added FoxMetrics and tests
removed unused values and some minor updates

When using segment.io and calling ga, there are two missing arguments (which I take advantage of)
So I added those two calls:
 properties.value,
 properties.noninteraction
adding event tracking to clicky integration
removing trailing comma
Updating gosquared, hopefully fixing travis
Re-arranging min tests
Updating makefile to add phantom variables
