use nodejs v0.10.33 and python 2.7.6

Please use ndenv for nodejs versioning and pyenv for python versioning
Your .node-version tells ndenv that it needs version v0.10.21 but v0.10.21 has an old npm (1.3) so I get an error that I need npm 1.4+. I bumped the version of node to the current version v0.10.33 and the build passes. Also, I see you need python 2 so I used python 2.7.6 and it worked. Please use ndenv and pyenv for managing your python and nodejs versions. It's easy to use and it's friendly with other projects on the same system.
