I think this needs to be in quotes, otherwise it was screwing up something with rounding down to 0.1, iirc. /cc @jrgm

@pdehaan I've addressed both of your comments.

@pdehaan should we do the same in the customs server? I copied its .travis.yml into the auth-mailer.

[pdehaan]

@fmarier Sorry, I'm an idiot. We don't need to add --depth 0 since it's calling npm run outdated which is a script in package.json which adds the depth for us. No need to tweak customs server.

Sorry, I have failed you.

FWIW, here was the 0.10 vs "0.10" issue I was remembering: travis-ci/travis-ci#977

Not sure if that's super valid or if they've addressed it somehow as it looks like fxa-customs-server/.travis.yml specifies 0.10 (no quotes), but the Travis logs show:

$ node --version # v0.10.32
$ npm --version # 1.4.28

Alright, let's give it a go like this.
