Add support for on-device live reload

[sinedied]

To smooth out even more development of mobile app, we should add a new npm command to allow live reload dev workflow on mobile device, using:

• https://github.com/nparashuram/cordova-plugin-browsersync
• angular-cli build with watch feature asnowwolf/angular-cli@d91a2ad#diff-bf508ac5f40d79d6bcbe0b996b75ca5d

It should be "just" a matter of integration.

EDIT: Compatibility with Ionic DevApp is another interesting option: http://blog.ionicframework.com/announcing-ionic-devapp
We should take a look at what the ionic-cli does to communicate with the app and see if we should integrate the same thing.

Did you look into supporting Ionic DevApp?

[sinedied]

No, but that could be an option now that Ionic is based on regular Angular CLI. Is Ionic DevApp still available on iOS, I though it was taken down by Apple?

[lgadola]

It's still there. I just downloaded it.
