Added support for build errors: now build errors get reported as build failure and the image is not created. Previously, build errors were being ignored.
Improvements:
Fixed multiple typos
Added more details on how apps internally can talk to each other
Added functionality to disable "Expose As Web App". Now if you are deploying an app that's only being used as an internal service, you have the option not to expose it via a public URL. This is also useful when in the next release Captain starts supporting databases as they are web-apps at all.
Added underlying structure for supporting databases. Since it's not thoroughly tested, the UI is still hidden.
