Run test suite using karma

[megawac]

Me and @akre54 were discussing this yesterday on this commit megawac@bea414e

This commit makes travis test using Phantom, Chrome and FF. Later we can do sauce as well

A later commit can omit phantomjs from the dev dependencies (which would be sweet!) and assume the user has firefox installed. This assumption would allow people to omit the 13MB buggy install every time and if they dont have ff they can use chrome or opera or whatever else they want no probs.

We did this a couple days ago on underscore as well jashkenas/underscore#2054

Chrome failed on Travis. Any ideas of how to handle this?

Also I removed the test-amd.html file since it's pretty much superfluous. If you pull in master you should be up to date.

@akre54 just karma-runner/karma#1144 had to run in sandbox apparently

I'm all for using a real browser for testing instead of phantom. 👍

We still need to swap out the npm test script and add karma-cli to package.json right?

No need to add karma-cli as a dependencie,

"scripts": {
   "test": "./node_modules/karma/bin/karma start --single-run"
}

in the package.json does the trick.

Awesome. Let's get to fixing #3434 now.
