Google Analytics cannot authenticate from Travis

[cboettig]

Travis build fails when google authentication is turned on (https://travis-ci.org/cboettig/labnotebook/builds/23059577). Google complains that the device isn't recognized and could be a hacker. I've filed the authentication problem as an issue in garb, in case its developers have seen this: Sija/garb#33

I could also consider migrating to the somewhat newer legato gem for analytics. Not sure if that would help work around this problem or not.

Must try the new jekyll plugin from developmentseed for this and see if that works instead: https://github.com/developmentseed/jekyll-ga
