Merge pull request #10 from spendflow/master

Update for Meteor 0.6.6.

Got rid of needless (and possible overwriting of) global environment variables.
Merge pull request #12 from srounce/master

User environment variables are overwritten
Makes meteor.sh exit on errors.

This helps fix that, as per this article - http://robertmuth.blogspot.pt/2012/08/better-bash-scripting-in-15-minutes.html.
