runtests.sh is not downloaded with executable permissions about elm

Also: if you're like me, you ended up here wondering why you couldn't run the tests.

This link helped me understand chown enough to get them running.

I'm willing to sit down this weekend and update the README for this track to walk newbies through how to make the .sh files executables for Linux and Mac users. I'm not sure what the appropriate way to describe running a .bat file in windows. Enter the filename from a cmd prompt?

@Calvyn82 thanks for reminding me about this! I'm really unhappy with asking people to modify the runtests scripts every time they download a new exercise.

I'm almost tempted to switch back to recommending elm-test-runner, with the caveat that it shows an odd error message at the end. It does look like rtfeldman is planning to update soon: https://github.com/rtfeldman/node-test-runner

If we want to stay self sufficient, I think I'd prefer to write a little node powered wrapper. Thoughts?
