Add "Notify" Ability

[burkeholland]

If it's decided that #29 is a good idea, we should notify users when things have failed or there are errors. This could additionally be configurable.

Since we already require Chrome, we should be able to do this with the notifications API? Looks like Chrome is deploying a new "Notifications Center" with Chrome 28.

Great idea!

Seems the Chrome notifications API is available only for Chrome extensions and packaged apps, which isn't the case of the bootstrapper.. Any case, there has to be some CLI tool that the bootstrapper could call... still looking into this.

For now when things fail the notifications show up in the bootstrapper console.
