add jasmine

[testdouble]

We should probably have jasmine. I'm pretty sure I'm under contract to never publish anything JavaScript-related without it.

I really dig this for one-time runs. If a failure occurs, it knows to break the build, but b/c it uses grunt.warn, the convention is you can "--force" your way past the warning, so if you want to ignore test failures you can.
