Exit codes for Ionic

[cincuranet]

I'm trying to script whole build-test-stage-publish process using Ionic 2, but it's really difficult because running i.e. ionic build ios always returns 0.

It should return some non-zero exit code when some error occurred.

Hello, since this is an issue with our cli and not the framework I have moved this issue to the appropriate repo. Thanks!
