Add module to scrutinizer

[chillu]

Could you please add the module to scrutinizer? https://scrutinizer-ci.com/g/new. We're keeping track of all modules we use on our contributions dashboard (github-dashing.herokuapp.com), and I've added scrutinizer quality and coverage scores there. Doesn't require any config, just four clicks. You'll have to click "Schedule inspection" for the first run, after that it should kick off automatically on commits.

There's banners you can copy paste into your README if you want. Also, if you feel like it, you could also add me as a collaborator :) There's a "Add collaborators to your repository" option on the homepage.

We're experimenting with a more fine tuned config, including code coverage running on travis, but that's not really to roll out yet (https://github.com/stojg/silverstripe-timeline). Happy to hear feedback and get help of course :)
