Open server on course page instead of main folder

[hanshillen]

Every time f I run rub -s my-course-name, rub opens http://localhost:3001/ and I still have to manually navigate to /builds/my-course-name/index.html in the browser from there.

It would simplify the process and save a lot of time if rub could just open http://localhost:3001/builds/my-course-name/index.html directly in this scenario.

I've changed this locally in commands/070server.js, but it would be useful if this could be the default behavior.

What do you expect to happen with the following commands?

1. rub -s my-course-name my-course-name2 (multiple specified courses)
2. rub -s (no specified course)

For 1 I would expect to open the first course, for 2 I would expect it to do what it currently does (or maybe start in the builds folder).
