Allow displaying warning even on successful builds

[mdevlamynck]

It would be very nice to have the compiler warnings even on successful builds.

Currently the only way to get these warnings is to have a failing build (they are present among the error messages). elm-make will print them even on successful build so I guess the loader is just not forwarding the compiler output (showing only the warning and not all the output would require parsing the output to find the warning section). I don't know much about how webpack works, do you think this is something doable?

I'll try to take a look at the loader's code to see if I can hack something into a PR.

Probably this has to be addressed in rtfeldman/node-elm-compiler, there's an issue for that on the repo. You are very welcome to leave feedback there.

Compiler warnings are being removed in 0.19 and it's not certain they'll be re-added, so it's probably best to hold off. 😄

Thanks for the reply, that's a good point!

I'm assuming this one can be closed, because of #142 🤔
