Update Tests for Elm 0.14, elm-package, elm-make, etc.

Currently a test is failing in the Array test file, but the error reported is a pattern match failure in Dict.elm, so it could be either a Dict bug or the Native Array code is producing an invalid object somewhere.

See the .travis.yml file for how it works, but the most important line to note is https://github.com/maxsnew/core/compare/elm-lang:master...maxsnew:tests?expand=1#diff-354f30a63fb0907d4ad57269548329e3R21 , where I filter out calls to `appendChild` because they mask any actual errors that the program has. It would be preferable if these never happened in the first place.
