Fail compilation when strings are missing

[garma83]

Clear and concise description of the problem

Right now, I have a big application that uses single page components, that contains about 2000 strings, and has 3 translations. It is very hard to track down missing translations. It would be nice if a fatal error would be thrown when a missing string is encountered during web pack compilation.

Suggested solution

provide a setting that allows fatal errors when strings are not found.

Alternative

manual tracing of missing translations
