Merge pull request #1 from gs-akhan/master

Added instructions for installation
Attempt to update npm before running the tests.
Removed node version 0.8 from the build.

Until travis allows npm to be updated to version 1.4.x, all version 0.8 builds
are broken. This removes 0.8 from the script to get things back to green.
Updating npm works..

The tests were delayed and made me think this failed.. so it's back!
