Build fails on node.js 0.12 and io.js 2.5.0

[papandreou]

After I added node.js 0.12 and io.js to .travis.yml, the build started failing on those platforms: https://travis-ci.org/One-com/livestyle/jobs/73107760

So the failing build is probably not a regression, but at least we know that it doesn't work there now :)

node-sass in a really ancient version. I'll take a look at it
